Phosphate buffered formalin. 40% formaldehyde: 100 ml. Distilled water: 900 ml. Sodium … Zinc Fixatives - ANATECH LTD Zinc formalin fixatives improve general morphology and immunohistochemical staining. They can reduce or eliminate the need for antigen recovery procedures while preservng immunoreactivity for months. All f our zinc products are compaatible with all tissue processors. They may be used in place of neutral buffered formalin. Zinc Formalin Fixative, Unbuffered Zinc Sulfate Discard Zinc Formalin Fixative accounting to local and state environmental regulations. Zinc Formalin Fixative can be neutralized with magnesium hydroxide/oxide, sodium carbonate or sodium bicarbonate to precipitate zinc at pH 7.0-8.0. Approximately 100 grams of sodium bicarbonate will precipitate zinc from 1 liter of Zinc Formalin Fixative.

Formaldehyde/Zinc Fixative Technical Data Sheet

The ratio of formalin volume to tissue volume should be at least 10/1 but should not exceed 20/1. * PRW provides prefilled Zinc Buffered Formalin containers in a variety of common sizes, including 20mL, 40mL, 60mL and 120mL.

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

Formalin fixation - Tissue sampling, processing and staining

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.
