[Histonet] Non Formalin fixatives

[pmarcum <@t> vet.upenn.edu]

Gayle is right it can reduce your disposal cost and will pay for itself in a
short period of time.  Also with formalin subs you have to be sure none of your
antibodies are linked to an FDA protocol that requires formalin as the fixative
for a specific drug to be given based on the test results.  You would need to
re-titer or check every antibody against your formalin results to be sure they
will not need adjustments.  I am hoping to begin recylcling next year dispite
the fact we get our alcohols through the university for a very good price.  The
cost of xylene and xylene substiutes is still high.
