Use your standard processing procedure, I have used this for 
demonstrating urates on tissue fixed in 70%, 100% alcohol and in 
chronic conditions some will remain in formalin fixed tissue          
( although I would recommend the alcohol for the urates and if 
sufficient biopsy is available, some in formalin).            
Gomori's methenamine silver on the paraffin sections will show the 
crystals clearly.
