RE: [Histonet] RNase contamination during in-situ

From:"Edmondson David \(RBV\) NHS Christie Tr"

30% Hydrogen peroxide diluted 1 in 10, for ten minutes and rinse glassware with Methanol,,, was what we were advised to use and the slides appear to be not a problem.     Do folks agree??

The reagents in the kit should not be a problem.

The wash/diluent water could be double distilled but the high grade supply for the Bayer analyser in Biochem seems fine

surfaces, glassware and reagents?  Any and all suggestions would be
