[Histonet] Double labeling with antibodies that need different fixatives

[Adam .]

Although I haven't tried it myself, others have gotten CD31 from BD to work
on FFPE tissue using the tyramide amplification system on zinc buffered
formalin fixed sections. I've generally had good luck with zinc buffered
formalin myself for many antigens so it may work for your other one.

See http://www.ncbi.nlm.nih.gov/pubmed/19052548

Just to be clear, they used zinc buffered formalin, which isn't the same
thing as zinc fixative.
