You have to anesthetize  the animal first so the lungs will not claps, then open the chest cavity, make a small incision in the left and the ventricle, using a plastic syringe very gently inject PBS Ph 7.4 till the blood clears, the introduce the fix. We used that method to perfuse feline and swine as well as mice and rats for LT and EM.

I am processing whole fetal mouse samples (these are pretty big, they have
skin developed) and the investigator wants to have sections so that both
lungs show up at the same time in the same section.  Can someone recommend
to me a way to dissect these to open them up so that they will fix and
process well but still maintain the whole body architecture for sectioning.
Thank you,

Patsy:
Many years ago I had to do that. Of the three "classical" sectioning planes (transverse, sagittal and frontal) the one to use is the frontal. Rest the embryo flat on its back and cut it open starting at nose/mouth level all the way back to the vertebral column in a way that the back half of the embryo can be separated from the front half. Try to harden it first with formaldehyde (4-6 hours will be enough; you should also inject in the abdomen a little amount of NBF also).
 Try to leave as much material in the front so you will get to cut to the lungs when trimming down the block. I recommend you also to process it enclosed in a cassette that keeps the structures in place, and to extend the times, not so much in the dehydrating as in the infiltrating steps.
Had you been using the dehydrating/infiltrating steps I used to use (ethyl alcohol/isopropyl alcohol/mineral oil) you would get a better infiltration.
Hope this will help.

Hi all. I have a question about an antibody to Pax2. We have just begun to
try to work up this antibody. It is supposedly upregulated in renal cell
carcinoma, so it should be positive & it has been. From the reading I have
done it should be negative in normal adult kidney. Our current problem is
that we are seeing staining on normal adult kidney. Any help or ideas are
appreciated.

Dear Hal Hawkins,

The endothelium of lymphatic vessels can be stained by
enzyme activity histochemistry. The enzyme is a
5-nucleotidase (belongs to the phosphatase family).
Ordinarily this type of method is carried out with frozen
sections of tissue that has been minimally fixed in
formaldehyde or glutaraldehyde, or with unfixed cryostat
sections that have been briefly fixed in cold acetone. The
enzyme in lymphatics may be fairly robust because its
activity can survive embedding in glycol methacrylate. 

The references below may help. If you choose one of these
methods it will be important to consult the original
publication because there's more than one sort of
5-nucleotidase. Each ref is followed by brief notes that I
took when reading the papers. [An R in the acquisition
number means I've got a Reprint of the whole paper; an A
usually means I have a copy of the paper's Abstract. No
letter with the acquisition number usually means I've seen
the whole paper and took notes in the library.]

I read Dr. Kiernan's post with much interest. Has anyone on Histonet had

Several suggestions:

- Cut slower (real slow; real, real slow)

- Cut the blocks at room temperature (not iced/chilled). Chilled is great
for getting thiner sections, warmer for thicker sections

- Might have to change the knife angle. Try cutting an "empty" paraffin
block (make a block with no tissue), and increase and decrease the knife
angle, until you can get sections without wrinkles from the plain block of
paraffin. 

- If all the above fail, float the section in a container of 25% alcohol,
then pick the section up on a slide, drain the slide of the alcohol, and
slower lower the slide almost horizontal into the warm water flotation bath.
The folds need to be parallel to the surface of the water bath, not
perpendicular, in order for them to be pulled out by the difference in
surface tension between the water and the alcohol. If 25% alcohol is ripping
the section apart when laid on the water, try a lower percent of alcohol.

Let us know what worked for you, so we all can learn.

Hi,

Does anyone have a GFAP protocol for a fluorescence method that they could
share?

Many thanks

Does anyone use a Labconco (or another)hood to do staining of H&E's?  We recently moved into a new facility and when we moved none of our stains worked right.  We have not completely ruled out the water change but we now have purchased stain(instead of making our own) and the stain is good.  It would really be helpful to get feedback on who has the entire staining set up under a hood in comparison to only the xylene under the hood.  We also have had the problem of a Labconco hood that we purchased that is supposed to move the height to adjust to different size people using it.  It's a great concept but Labconco did not supply the ventilation tubing to make it moveable, thus we are stuck with an expensive hood that doesn't move.  Any ideas????  Thanks for your help.

What is the best fixation for smears from a fat-pad of a patient suspected

Hello everyone!

I have been looking in the archives and am still a bit confused. I have
a friend who has asked me to find out who may perform IHC in her lab...
Would you say the following is correct as to who can perform IHC?

BS or MT/HTL
AS in science HT or MLT
Prior to 24 April 1995 HS graduate AND Military training (50 wks) and
classified as a Medical Laboratory Specialist
                                                       OR  Graduate of
an accredited lab/histology program.

Based on the above, I am interpreting that I currently have several
techs that cannot perform IHC. Two are HT(ASCP), one HS/OJT the other
GED/OJT. Neither with any college, military training, nor attended an
accredited program. These two cannot perform the testing. I have two
trainees, one has an associates, is an MLT, and is currently sitting
for his HT. (I think he is okay, or does he have to wait to pass his
HT?). The last is another trainee that has not completed her degree
yet, so she has a ways to go yet. She will have her BS in May, then
will sit for her HTL. Once she has her BS, she meets the requirements.

Does all of this sound correct?

Thanks for any and all help!

Hi Histonetters,

would any one have experience of counting granules in mouse mast cells in 
tissues which have been formaldehyde fixed, decalcified in a formic acid 
based solution, post osmicated and embedded in epoxy resin?  I'm taking 1 
micron sections and looking to assess the 'degranulation' status of each 
mast cell in terms of how many are still dark blue and how many are pink 
ie based on the metachromatic properties of toluidine blue.  I suppose my 
question is will the formic acid have altered the dye binding properties 
so that I'll get erroneous results?  I'm going to experiment with tissue 
that does not normally have this step but any insights now would be most 
welcome.

Many thanks

I've had a look at some journals on the web, but would appreciate some

Try increasing the cutting angle; cutting more slow and cooling the cutting surface inmediately before the section you are going to take.

Although it could be considered as a "biassed" opinion I would suggest for you to look at the Journal of Histotechnology from the National Society of Histotechnology.

Hi everyone, 

is anyone familiar with CAP #ANP.22925 
"For IHC tests that provide independent predictive/prognostic information,
does the patient report include info on specimen processing, the antibody
clone, and the scoring method used? (e.g., hormone receptor in breast
carcinoma, HER-2/neu, EGFR).
"The lab should periodically compare its patient results with published
benchmarks, and also evaluate interobserver variabitlity among the
pathologists in the lab".

how are others handling this??

Many, many thanks in advance,
