Cc: histonet@lists.utsouthwestern.edu Subject: AW: AW: [Histonet] Control slide storage I think the culprit is a "kind of oxidation" the epitopes suffer from. But it would be interesting, if the fixation is a factor of influence, or if the composition of the epitope itself makes the difference. Gudrun -----Ursprüngliche Nachricht----- Von: Edwards, R.E.

And I'd like to ask all the other listmembers about their experiences with this issue. Perhaps we can make a list of "dangerous" epitopes.

What experience has anyone had on the effects of long term storage and staining quality. We store the slides non preheated (with the paraffin still on them).
