Phagocytosis and
pathogen killing
Purpose of Histology Lab Report
The main purpose of this lab is to
identify different types of bacteria and also what are the methods for the
macrophage intracellular killing.
1. Why
did we conduct the exercise?
The
main aim of this exercise is that the students can easily able to measure the
basic ability of the macrophages. The macrophages can able to kill the bacteria
that have been phagocytosed in more than 24 hours period. Then after this make
a list of the surviving bacteria by just laying the macrophages and after this see
the bacterial growth to occur.
2. What
information were we trying to obtain?
From
this lab the students have got the special information that how they can able
to kill bacteria through the use of macrophages.
3. What
concepts were being demonstrated?
There are
different steps that are demonstrated in this lab include the role of
macrophages in killing the bacteria. The process of phagocytosis is explained
in detail with different steps and also some other process named chemotaxis.
Information about the receptors found on the macrophages. The most interesting
concept that has been discussed in this lab is about the pathogen that is when
different pathogens types trigged a response so as a result unique pathogen
characteristics came into being.
4. What
protocol, method or technique did we use to obtain the information?
The technique the
students have learned from these labs is how the macrophages able to kill the
bacteria and examine the killing activity of the macrophages.
Procedure
·
There are two parts of the procedure and in the
first part of the procedure is about the students have to go outside and
collect some samples of the bacteria.
·
Then after this takes 12 well plates for the
microscope in which the macrophages are growing at the bottom of the plate.
There are six well in which different cells are present. You must have to mark
each cell so that there will be no mix up of the cells plates.
·
Then after this take a tube with E.coli bacteria
present in it with proper concentration. Then put this on the plate and you must
make a dilution of this E.coli culture so this will help to see the desired
number of bacteria under the plates. Then after this the students are provided
with 5ml if media and that will help to calculate dilution of your bacteria so
by the help of this dilution the macrophages will able to eat 10 bacteria
easily.
·
Then after this by the use of P1000 pipette and
then with the help of this remove the existing media from the plates. Then add
300ml of media that has contain correct amount of bacteria in it and then after
this cover the lid of these slides with the help of this media and then in the
end place this plate 37 degree CO2 incubator and allow these
bacteria to keep for only one hour.
·
Then after one hour you will able to get your
plate and then the next task is to remove the media from the plates. After this
just add one ml PBS to each of the 6 plates and also swirl the plates slowly
and also wash these plates.
·
Then after this remove the second PBS with the
help of pipette and then add 500ul and then return the plate to the incubator.
The main purpose of this step is to kill the bacteria easily without
macrophages.
·
Then after 30 minutes these plates are transferred
to the 1.5 ml tubes and also make sure you must have to label these tubes and
remove the PBS thoroughly.
·
Then after this repeat the same process on the
next day by collecting different samples then you must label all the samples
and then put these samples in the ice bucket at the front of the room so the
instructor will store these samples for the next week.
Discussion and conclusion
1.
What do you expect to see once the CFUs
are performed in your samples? Which sample will have the most CFU/ml of
bacteria?
There are 12
slides on which this experiment was performed but only in the 3 slides in which
the macrophages are growing at the bottom of the plates. The sample which was
diluted with water and kept for a whole day this sample has the most CFU
bacteria this sample.
2.
What problems were encountered, if any?
There was only one problem that has
been encountered during the experiment is that the macrophages and the media
are not completely diluted in the well so because of this the required results
are not obtained.
3.
Was the purpose of the experiment
fulfilled? Were the objectives listed in the purpose section accomplished? Why
or how?
Yes, the purpose of this lab was to
kill the bacteria by the use of macrophages has been completely fulfilled
through following these above steps. Also the results that are mentioned in the
objectives are also covered because all the steps were followed in a correct
way.
Procedure for lab 3
·
In the first step you have obtained the plate in
which there are bacterial growth samples. Give 3 samples to each group that was
mixed with water and after this add 500ul LB liquid media to these three tubes and
mixed with water so that their total volume will be equal to 1 milliliter.
·
For conducting the next step the students must
provide with the six new tubes and then after this add 900ul of LB in each
tube. When this is done the students must have to label each tube.
·
Then the next step is about to perform serial
dilution for this you must add 100ul from your original tube and then after
this transfer this solution to the first label tube and then after this mixed
the solution and move it to the next labeled tube 1:100 tube.
·
Then label these tubes on the bases of hours,
then after this put all the label samples on the single plate and add 50ul
sample containing the original and diluted bacteria and then identify the red circles
under the microscope.
·
Then after this in the next step dry both the
plates for some time and then put the agar plate in a 37 degree standard
incubator for bacteria. Then after this wait for a whole day and in the next
day you have to come to count the colonies on these plates so that because of
this you can easily able to identify these surviving bacteria.
·
The next lab exercise is for determining plague
forming units and for that this can easily been determined by the use of plaque
assay.
·
For determining the plague forming units you
must have to count the number of dead spots in a given plate. Then after this
figure out the total number of undiluted samples, then after this count the
diluted samples by just divide and conquer.
·
In the final step you need to graph the results
in your note book.
Conclusion on Histology Lab Report
1.
Interpretation of CFU data. What
differences do you see between the samples? Why do you think these differences
occurred?
In
the first CFU there are some bacteria are present after adding dilution in them
and then after this when the time passes you have seen after 1.5 hours there
are a lot of bacteria present and when the time passes after 24 hours you have
noticed that there are very low amount of bacteria present in the slide and
after a week in the CFU there is no sign of bacteria present in it.
2.
What conclusions can you make about the
different mice that these viruses were isolated from? What about the immune
response in the mutant mice might cause the differences?
(Hint:
the difference in virus titer only happens late in the infection)
When the cells grow after this
these cells are infected from the viruses and after this the virus will grow
further and kill all the cells.
The immune response of the mutual
mice after the infection and when these infections in the cells are isolated
with the virus so this can be seen under the microscope that because of this
virus isolation all the infected cells that are present in the mutual mice will
be dead and this can be seen that these cells are free of any infection.

SDS-Page and Immunoblotting
1.
Why did we conduct the exercise?
The main aim of this exercise is to
obtain the information about the antibodies and these are widely used in
different industries. Also how these antibodies are implemented in different
industries.
2.
What information were we trying to
obtain?
The information about the antibodies
and also about the most powerful analytical procedures and this procedure named
as the immnoblotting. For this procedure how to make mixture of proteins that
has been separated from electrophoresis. When these are separated and how these
are transferred to nitriocellulose sheet. Also from this lab the students are
able to know about the electrophoresis of proteins.
3.
What concepts were being demonstrated?
There are different
and important concepts that have been demonstrated in this lab. The first
concept is about the separation of different proteins. After this the most

electrophoresis of proteins carried out.
4.
What protocol, method or technique did we use to
obtain the information?
Experimental
technique will be carried out through the use of different equipment.
Procedure 4
·
In the first step add gels for the SDS-page are
assembled in the electrophoresis gel boxes and then for loading these samples
this gel has been prepared.
·
Then after this in the next step you will find
the solution about the molecular weight marker then after this they are loaded
with the SDS and 2-ME mix them and load them into the gels.
·
Then in the next step these gels samples are
given to each of the group and then load 2ul of molecular weight marker in the
most available well and then after this load 15 ul of Macrophage into the well
for 0 hour, 1.5 hour and also for 24 hours.
·
Then after this in the next step these gels are
loaded and then connected with the power packs for 60 minutes and 120 voltages
are given.
·
Then in the next step when the gels are
completed so you must remove from the glass carefully and then these gels are
then carefully placed in the glass plates.
·
The next step is for setting the transfer and
this can be done by take a PVDF membrane and then after this socks it in the
methanol tray for few seconds. And then after this just you have to remove this
membrane and placed it on the shaker for just 5 minutes.
·
In the next step the students have to make a
sandwich by using the PVDF membrane and also the SDS-page. For conducting this
step you must place all the components according to the required order and in
the first there comes a sponge and then after this there comes filter paper and
the in the middle there is PVDF membrane
·
In the next step there is working of the
previous step and in this there are western blots are present and these are
then electro transferred from the gel to the PVDF membrane and this can be done
for 40 minutes and for 40 volts.
·
Then in the next step is to obtain the clean
tray and add 10 ml of blocking buffer and then after this collect your PVDF
membrane strip and then after this label this strip and place it on the shaker
for more than 30 minutes.
·
Then after the 30 minutes remove the required
sample from the shaker and pour this blocking buffer in the sink. The students
must have to be extremely careful while pouring this into the sink. Then in the
last just add 10ml of primary antibody and finish this process.
Lab 5
Purpose
1.
Why did we conduct the exercise?
The main purpose
of this exercise is to experimentally check the secondary antibody solution and
also see what will happen to the secondary antibody when it is contact with
super signal fempto substrate.
2.
What information were we trying to
obtain?
In this lab the main information
for the students is about the antibodies that how they mixed with the proteins
the most powerful analytical procedures and this procedure named as the
immnoblotting. Also, what will happen when you add secondary antibody solution.
3.
What concepts were being demonstrated?
The concepts from this lab are the same
because the theory is same for both of these labs. The first concept is about
the separation of different proteins. After this the most important concept is
about the electrophoresis of proteins and also how this electrophoresis of
proteins carried out
4.
What protocol, method or technique did we
use to obtain the information?
The experimental
technique is used to obtain the required information for this lab.
Procedure
In the first step
you have to pour the same primary antibody solution from the previous lab in
the tube and then wash the PVDF membrane with the help of 15ml of TBST
Then in the next
step you have to add 10 ml of secondary antibody solution to the sample box and
put it on the shaker for 45 minutes.
Then wash 15 ml
TBST again and put it on the shaker.
When you have wash
it then after this just add 10 ml of TBST so that because of this membrane will
not dry.
Then by the help of
digital imaging system the students have to take picture of the light that has
been generated by Peroxidase enzyme and it is attached to the secondary
antibody. Once you have got the picture from the imaging system then after this
you have to pick PVDF membrane and then after this place it between the two
layers of the plastic sheet.
Then after this you
have to add just one ml of substrate to the PVDC membrane and then close this
sheet and put this in the imager.
In the final step
you just have to past the images on your note book and also label it according
to your samples.
Results
In the left side of picture there is
experimental sample of the total lkB-a and this is also inactive. It can easily
be seen that when you have mixed 39kDa then after 0 hour there is black spot
can be seen and then after 1.5 hours it can easily be seen that this spot is
still black and then after 24 hours has been passed for this sample so this
will turn into grey spot.
In the right side of the picture
there is experimental sample of the phospho-ikB-a and this is active. So
because of this activeness it can easily been seen that this image is more dark
then the inactive one. It can be seem that when phospho is mixed with the Actin
(42 kDa) so after 0 hour it can be seen that there is grey spot and then as the
time passes after 1.5 hours this spot is still grey and then after 24 hour this
spot is converting from grey to black color. After this when you add 40 kDa
phospho-ikB-a so in the initial hour of the experiment there is no spot can be
seen. Then after in 1.5 hour a black spot can be seen and then in the end after
24 hours it can be seen that this black spot is turned into grey.
Discussion/conclusion
a. Why were the samples boiled?
The
samples are boiled because when these samples are placed for digital image
processing the images are not clear so this means that when you want a clear
image of the sample so for this all the samples must be boiled.
b. Why did the instructor add
SDS and other reagents to them?
The instructor adds SDS and other
reagents because he doesn’t want the samples to be dry off quickly. If these
samples are dried so proper exact result will not be obtained.
c. How were the proteins separated?
The
mixtures of different proteins are separated by the use of electrophoresis
through a polyacrylamide gel.
1. What
was the purpose of incubating the membrane with milk? What was our primary
antibody?
The
purpose of incubating the membrane with milk is just to convert the remaining
capacity of the PVDF to bind proteins.
2. What
was our secondary antibody?
Our
secondary antibody is conjugated to an enzyme like alkaline phosphatase
or horseradish peroxidase.
3. Draw
a figure representing the Western blot process ( include your membrane, primary
antibody, secondary antibody, HRP, substrate )
1.
Describe your results and what they indicate
for the NF-kB signaling pathway.
In
the left side of picture there is experimental sample of the total lkB-a and
this is also inactive. It can easily be seen that when you have mixed 39kDa
then after 0 hour there is black spot can be seen and then after 1.5 hours it
can easily be seen that this spot is still black and then after 24 hours has
been passed for this sample so this will turn into grey spot.
In the right side of the picture

phospho-ikB-a so in the initial hour of the experiment there is no spot can be
seen. Then after in 1.5 hour a black spot can be seen and then in the end after
24 hours it can be seen that this black spot is turned into grey.
2. Were
there any unexpected results? What are possible explanations? Indicate things
that might be done differently if the lab were repeated.
No,
there are no any expected results. The voltage must be different when this lab
were repeated again in the future, in this lab the voltages are set at 120
voltages and for the next lab these voltages must be turned to 110 so because
of this more proper results can be obtained.

Procedure
·
In the start first six steps are just for the
students’ information.
·
Now from the next step the students have to
transfer just 100 ul of the standards to their ELISA plate and also add 1X
ELISA assay to the blank wells.
·
Then after this just add 100 ul of your media
that was collected from the lab 2 and then after this cover the plate and save
these plate at room temperature for 20 minutes.
·
In the next step you just have to dump all the
contents of the plate into the graduated cylinder and this cylinder is
completely contaminated with the bacteria E.coli. Then after this wash it by
just adding 200 ul of wash buffer and then just repeat this step and put it on
the dry towel.
·
Then after this just you have to dilute your
stock detection antibody. Add just 100
ul of detection antibody. This antibody is dilute in 1X ELISA assay with the
ratio of 1:500 and the total volume can be calculated easily by the use of this
formula
·
·
Then after this just wash these plates, and then
dilute your stock streptavidin-HPR and just add 100 ul of streptavidin-HPR and
again this is dilute in 1X ELISA assay diluents. Now after this you have to
wash it four times.
·
Then in the step you have to just add TMB
solution to each well and then save these wells at room temperature until the
color of these plates turn dark blue.
·
Then in the next step you just have to add 100
ul of stop solution to each well.
·
Then in the next step you have to view this
plate under 450 nm microscopes.
·
Then in the final step you just have to make
table of your reading on your note book and also explain these graphs.
Results of Histology Lab Report
This graph is
according to that diagram because in this diagram the A row represent the
concentration of the standard and the second row is about the stock of the
dilute solution.
This table
represents the whole experiment that has been performed above and in the first
column of this graph there is information about the well ID that on the basis
of these IDs ELISA assay has been added in them. Then after this in the third
column of this table there is information about different well and with
numbers.
In the third column
of this table there is information about the concentration and dilution and you
can see that we have just concentrated the well number B1, B2, B3, B4, B5, and
B6 only
In the fourth
column of this table there is information about the Blank 450 and then in the
fifth column of this table there is information about the concentration of the
diluted solution when the stop solution is added in this. Then after this in
the next column there is information about the count.
In the sixth column
of the table there is calculation about the mean and in the second last column
of this there is information about the standard deviation what we have
calculated from this lab and in the last column of this table we have just
calculated the percentage of the CV
and that is 27.775.
Graph of Histology Lab Report
This graph is between the O.D and
the Mouse IL-6 the ranges for the O.D is from 0.01 to 10 and the range from the
0.1 to 1000. There is no response of the mouse IL-6 form 0.1 to 1 and after 1
it will gradually increase with respect to O.D and it can be seen that at 10
the O.D will be equal to 0.2. From the graph it can be seen that when Mouse
IL-6 is greater than 100 so it is going towards constant value of O.D.
Discussion of Histology Lab Report
1. Explanation
of the patterns that you see in the data and what it means
The
patterns that have been seen in this lab are obtained when an electric charge
is given and after this electric field has been established across the gel. The
charges are moving from negative to positive and the separated proteins that
are present in the gel will move towards the PVDF and this forming an identical
pattern on the PVDF sheet that are found on the original gel.
2. Discuss the signaling pathways involved in
producing IL-6 (how it was made, how long it took to be made, why and what is
the function of IL-6).
The
function of IL-6 is that they are responsible for stimulating acute phase
protein synthesis and also for the production of the neutriphils that are
present in the bone marrow. It is also responsible for growth of B cells.
3. Discuss
the differences and similarities between a western blot and an ELISA.
Similarities of Histology Lab Report
·
Both Western Blot and ELISA are depending on
detection of antigens from specific antibodies.
Difference of Histology Lab Report
·
One of the major differences lies in the Western
blot technique. In this technique the antigens are attached to membranes. These
membranes are like nitrocellulose membranes and all the important reactions are
performed on the surface of membrane.
·
In ELISA, these antigens are just attached to
multiwell plates. Due of this attachment the ELISA is extremely willing to
automation compared to Western Blot.
·
Another difference is that ELISA is a high trouped
technique; western blot is not so much.
·
The next difference is lie application wise,
ELISA method is used more in Medical diagnoses and Western Blot method is
highly used in research labs and other practical purposes.
·
The next important difference between Western
blot and ELISA is that the Western blot depends on enzymes for the antigen
detection and on the other hand ELISA don’t use enzyme for antigen detection.

mixture of macrophages in it and the concentration of these macrophages is
about 1x105
per ml.
·
Then in the next step you have put 500 ul of
cells into a tube and also labeled this tube. Then after this add 100 ul of
CFSE dye to these cells. When you put this then after that you must have to
shake them and cover them with the help of aluminum foil and save them at room
temperature for 20 minutes.
·
Then after this add 500 ul of fetal bovine serum
in it and then shake it on a machine.
·
Then after this in the next step you just have
to remove the cover carefully and then after this remove the media with the
help of pipetman.
·
When the media is removed from the tube and also
all the cells are now clean then after this again centrifuge it at 3000 rpm and
again remove that covering and add 1ml of PBS+10% serum again.

Procedure
·
For this you have to take 100ul of Splenocytes
and then after this place them in a tube and also label them.
·
Then in the next step you have to add antibody
cocktail about 100ul. In these antibodies there must be blocking agents that
will able to prevent these antibodies from attaching to the cells
non-specifically.
·
In the next step you have to save these cells in
the dark and placed them in ice bucket and this can be done by just covering
them with aluminum foil.
·
Then in the next step you need to centrifuge
these cells at 3000 rpm and carefully remove the covering on the tube. Then
again remove the supernatant and just add 1ml of PBS+2 serum.

did we conduct the exercise?
The main aim of this exercise is that to see
the process of cell death. And then in the next part there is flow cytometry
analysis.
2. What
information were we trying to obtain?
The
information about the death of the different cells, also see different types of
cell deaths.
3. What
concepts were being demonstrated?
The
main concepts are about the cell deaths and how to perform the flow cytometry
has been performed.
4. What
protocol, method or technique did we use to obtain the information?
For this lab flow cytometry analysis is used
for obtaining the information.
Procedure
·
In the first step of this lab the students are
supplied with two tubes each and both are labeled with A and B.
·
In the next step for viewing the dead cells you
need to add 100 ul of propidium iodine solution in it and then save these tube
under room temperature for just about 10 minutes.
·
In the next step you need to centrifuge that
tube at 3000 rpm. You have to carefully remove the supernatant. And then after
this you need to add 1ml of PBS+2% in the tube.
Part 2
·
In this part of the lab you have to perform the
flow cytometry analysis on the sample from the last part of this lab.
·
In the first step you have to analyze your last
samples on that flow cytometer. Then after this record all the data and paste
it on your notebooks.
