IHC Zinc Fixative is an alternative fixative to formalin fixation of tissue for paraffin embedded sections. 10% neutral buffered formalin fixes the tissue by cross-linking proteins that may cause a conformational change or "masking" of the antigenic epitope leading to reduced or absent antibody reactivity.
Jun 01, 2003 Zinc Fixatives - LabCE.com, Laboratory Continuing Education Zinc tris is a non-formalin, zinc fixative. Its fixative action is primarily from the zinc salts which are in a tris buffer with a pH of 7.2 – 7.4. It acts more like a preservative that prevents autolysis from proteolytic enzymes, instead of a fixative which increases the cells rigidity and thus tissue/cell morphology.

2. Prepare Zinc-Fixative as follows: 0.1M Tris buffer, pH 7.4 recipe above (1000 ml) 0.5g Calcium Acetate 5.0g Zinc Acetate 5.0g Zinc Chloride Mix to dissolve. The final pH will be approximately 6.5-7.0. Do not readjust the pH, as this will cause the zinc to come out of solution. 3. Store Zinc Fixative …
During embedding, a white deposit is noted on several of tissues. The tissues had been fixed in zinc-formalin, transferred to phosphate-buffered formalin, dehydrated with 65%, 95%, and absolute alcohols, and cleared with xylene. One possible explanation of the white deposit could be that the tissue was: Formaldehyde/Zinc Fixative Technical Data Sheet Formaldehyde/Zinc Fixative EMS Catalog #15675 .
