Dear Histonetters,
                                I have a query regarding the formaldehyde
substitutes ,Prefer,Preserve and glyco fixx .We are in the process of trying
out these alternatives and have been told by a Rep, that we would require
formaldehyde to store tissue samples .As we are wanting to eliminate the use
of formaldehyde in our laboratory is this the case?Does anyone out there
utilise these fixatives routinely and do you store your tissue in these
products .I know we could use 70% alcohol as a storage medium but this may
cause a fire risk.

Thanking you in advance
