Hi Fellow Histonetters/Safety Gurus,
     A question has come up in our lab about the fixation of HIV positive 
tissue....if left in formalin to fix overnight, then started on the 
processors in formalin, graded alcohols, paraffin and xylene is it enough to 
totally 100% kill the virus? I read an article today that stated formalin was 
"very highly effective" against HIV but it doesn't discuss tissue fixation 
per se.  So if anyone can offer any answers I'd appreciate it. Tim, since 
you're at the CDC I really want to hear from you on this matter......thanks a 
bunch!!
