Immunostaining for GFAP has been the definitive method for astrocyte cytoplasm
for 30 years, and good primary antibodies have been around for at least 20
years. The distinction between different kinds of astrocyte is made by staining
with serial dilutions of the primary antiserum. Reactive astro

good techniques. Im going to try them out myself :)

+1 to Linda, but I have found no difference on overnight vs multiple days.
Fatty liver is hard to do on all counts! It is tough enough sometimes to get a
decent section on the slide.
Thanks for the other suggestions, certainly something I would try in the future

Hi Tryrone
A Mass Trichrome stain will stain up the collagen in the diseased kidney. If
the tissue has already been fixed in Bouin's Solution you can omit the picric
acid step. Another good stain is the Curtis's Van Gieson Stain. Ive sent you
the protocol for botht he stains. Hope it helps.
Usually with the fatty tissues, I pick them up on superfrost slides and let it
air dry for 2-3 days at room temperature and then perform the ORO stains. So
far they seem to stay on.

Watch the liver, it will change color as the blood is washed out. Are you
perfusing first with PBS to rinse the blood out, if you start with formalin
small blood vessels and capillaries can become blocked by the blood that has

Hello,
Some questions regarding Bouin's solution.
I was told, back when I was doing my PhD and new very little, that I should
fix my fish in Bouin's as it will decalsify the bones. Well, Bouin's fixed
fish were easier to cut than PFA fixed fish... but I read today that by
adding formic acid the d
Hi Yves & Histonet
It is certainly a good sign if limbs etc are stiff after perfusion, but maybe
not a guarantee that the target organ is perfect given the short perfusions you
describe. Definitely, if I don't see stiffness I worry, check for a torn aortic
arch (you are doing it transcardially,
Thank you for suggestions for softening beak.
Yes, I actually processed the whole head for decalcifying first and then place
the sample in 10% KOH for 30 mins. It was my first attempt to process beak
(including a whole head) thus, i did not know i should have processed softening
beak first.

There are a couple of old techniques you might try.
1. Smear some Mayer's egg albumen on a slide as you would normally do,
i.e. very thinly, then hold it in a flame until it smokes. Allow to cool
and pick up the section. Allow to drain well.
2. Same as 1, but place the slide with the picked u
