Several queries about the possible effect of Davidson's fixative on immunohistochemistry.
I have a lot of experience with Davidson's fixative, but none with its effect on IHC. Davidson's fixative is easily prepared: 3 parts tap water 3 parts ethanol or reagent alcohol 2 parts 37% formalin (not neutral buffered formalin) 1 part glacial acetic acid It is quite destructive to H & E staining if fixation is at all prolonged. Tissue should be taken out of it in not more much more than 24 hours. The history of Davidson's fixative is somewhat obscure - I have a good bit of information on it. John Kiernan has said he'll work on ascertaining more about its history if he ever has the time.
