STF is no longer being sold.   Becton Dickenson Zinc IHC fixative is the 
next best choice as a replacement for anyone using STF for IHC.   I 
compared STF to BD zinc vs. Prefer - -tissues fixed in Prefer had greatly 
reduced signal (Murine CD31) than STF and the BD zinc.

Subject
[Histonet] Formalin substitutes






Dear colleagues:
  I have a question: besides BoonFix, GlyoFix, Histochoice, HistoFix, 
KryoFix, MicroFix,
  Mirsky'sFixative, NeoFix, NoTox, OmniFix (II and 2000), Prefer, 
Preserve, SafeFix, StatFix,
  STF (Streck Tissue Fixative), and UMFIX, which other formalin 
substitutes you know exist and/or have used?
  Did you all know that formalin is still the fixing agent of choice for 
81% of all histology labs (meaning the only 19% use substitutes)?
  René J.
