We supply the Dr.'s with Omni-Fix. (an alcoholic fixative) They are then
processed with NBF. We use Enzo's K903 AB and strong trysin digestion.

We're having trouble getting good nuclear staining and K9 IHC staining on
our prostate needle biopsies.
Clinician's offices fix them in 10% NBF. We put through 4 hour process with
zinc formalin in the first couple of stations as this enhances the nuclear
staining on our other tissues
fixed in 10% NBFbut not the prostate bxs for some reason.
Can you folks share what fixation gives you excellent H&E staining and what
K9 antibody you use
for IHC (our HIER is steam and we use Proteinase K pretreatment) ?
Appreciate your help-
