[Histonet] Zinc Formalin fixation

From:Gayle Callis

We never had a problem with tissue being brittle after fixation with the 
commercial Anatech zinc formalin (buffered) although I have heard others 
complain about this along with Liz's comments about precipitation problems, 
maybe in house prepared zinc formalin?  However, the zinc TRIS buffer 
fixative, that is FORMALIN FREE, for CD marker immunohistochemistry 
(Beckstead, J Histochem Cytochem) made tissues terrible brittle.
