[Histonet] pfa vs. formalin

From:MVaughan4@ucok.edu

Bryan,
Molecular Probes sells various phallotoxin probes that lose effectiveness 
binding to f-actin microfilaments when methanol is used as a fixative or 
is part of a fixative (10% NBF). For these purposes I dilute 16% 
formaldehyde, MeOH free, sold by Polysciences in sealed ampules, diluted 
1:1 with water, then that 8% mixture further diluted 1:1 with 0.2M 
Phosphate buffer pH 7.4. It works great as a fixative.
