Re: Immunohistochemistry on brain sections

From:Amos & Theresa <atbrooks@snet.net>

Hi,
    Since you are using formic acid on brain I assume you are staining for Beta
Amyloid, right? (Just a guess) We use the same procedure, but we do not
autoclave the slides. I'd try to eliminate one or the other. I have found that
compound retrieval techniques are usually harsh on the tissues, and formic acid
alone is harsh even with out the other procedures. If it is Beta Amyloid you are
staining we get good results with just formic acid. Let me know if I could help
further.
