[Histonet] alternative to Bouin's in Schiff-methylene blue nucleic acid

[Carla M Conway]

Hello,

A colleague is trying to determine the nucleic acid type of a rickettsial 
phage. Acridine orange with RNAse/DNAse treatment was not successful. They 
want to try a Schiff-methylene blue technique which requires hydrolyzing 
in Bouin's fluid (1 h at 60 C). Could anyone suggest another protocol 
which does not use picric acid (or suggest an alternative to Bouin's )? 

Also, any advice for nucleic acid differential staining would be 
appreciated.

Thanks very much,
