Hello. I want to do a Masson's trichrome stain on some rat arteries. I 
never did this before. All I know are the purpose and the principle. So 
I googled up a protocol from a website from which I had gotten a 
protocol for VVG, which worked pretty well on our frozen tissue. But 
this protocol mentions only paraffin sections. Would it work on frozen, 
aceton-fixed tissue? Here's a brief description of the protocol: 
Bouin's solution is used as a fixative (contains saturated picric acid, 
formaldehyde, and acetic acid). Hematoxylin for 10 min. Biebrich 
scarlet for 5 min. Phosphotungstic/phosphomolybdic acid for 10 min. 
Aniline blue for 5 min. 1% acetic acid for 1 min. Of course, all steps 
have washes. Then dehydrate, clear, and coverslip. Does that sound 
right for frozen sections? Thank you for your time.
