[Histonet] Antigen retrieval on very old tissue

[John Kiernan]

Ask for specimens from known negative and positive 
control brains. Try various antigen retrieval methods.

Process and immunostain + and - controls alongside 
sections of your "very old" material. 



The antigen of interest may not be retrievable
 after 
20 years in formalin. 

Just a few thoughts!
