[Histonet] Fixative and H2O2 for frozen

[Jorge Ivan Zapata Valencia]

Hello everybody
a technical question: may I use the same acetone:etanol mix to fix samples 
different days, or do I have to prepare it feshly every day?? The same with 
the H2O2 PBS solution for endogenous peroxidase blocking. Is it mandatory to 
use fresh one?
Thank You very much
