RE: quest. about fite's AFB
We also use the peanut or mineral oil/xylene to deparaffinize. It helps to
maintain the lipids in the organisms.
In addition we do use 1% acid alcohol (HCl in 70% ETOH) to decolorize, and
have had no problems with overdecolorization in our Fites.

Subject: quest. about fite's AFB
With the peanut oil/xylene step to deparaffinize, is a substitute clearing
agent like histoclear acceptable?
Secondly, just for my knowledge, what purpose does the peanut oil serve, to
simply maintain the structure of the organisms?
Finally, if I didn't have sulfuric acid to differentiate, would acetic acid
or HCl in water work, I figure they're too strong?
