[Histonet] RE: Antigen retrieval question

[Morken, Tim]

Brett, how long? I've left them overnight before proceeding without any problems. 

It would not be "re-fixation" as with formalin. However, if it is in a detergent buffer it might cause some other kind of denaturation.

Has anyone experienced a "reversal" of citrate HEIR unmasking do to a
prolonged delay in continuing the experiment after the retrieval step?
