[Histonet] Frozen tissue

[Anne Murvosh]

I'm testing a faster Mart 1 for melanoma on Mohs specimens. Its been a while since I've done any frozen tissue IHC stains and I can't remember the fixation to keep it viable for testing the next day, or same day but later on. Will it hold up if fixed in acetone and dried or do I need to refrigerate or freeze? Also how long do they last,  I can't remember the protocol. Thanks Anne HT
