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.

Zinc Acetate ----- 5.0 g Zinc Chloride ----- 5.0 g 0.1M Tris Buffer made above ----- 1000 ml 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. Store Zinc Fixative at room temperature. Scigen provides Neutralex Technology products as Formalin zinc, Filled neutral buffered, Formalin Neutralizer, Ultra absorbent containment pads, Pre-filled specimen jars, forma-vials, Neutra-Pads, Neutra-Guard in all over the California and Canada. Z-Fix is 10% aqueous buffered zinc formalin. It is used as a histological fixative. PRODUCT SUMMARY Z-Fix is designed to provide the desirable features of formaldehyde fixation without the negative effects of excessive crosslinking. Formaldehyde fixation is a two-step process. First,
You do not want to move them out of Zinc Formalin into regular buffered formalin. However she did say to rinse tissues in PBS or 70% EtOH, but PBS is a phosphate buffer so do not use that. Use regular water, DI or tap, instead. Then place it in alcohol or even regular buffered formalin. Do not put Zinc Formalin on your processor.
Buffered Zinc Formalin SDS Cytolyt SDS Shandon Cell-Fixx SDS Formalin-10% SDS Formalin. All of American MasterTech's Formalin and Formaldehyde products are guaranteed excellent quality tissue fixatives. Formalin has been widely used and trusted by histologists and pathologists for more than 100 years. It produces fixed tissue that is not only easy to work with, but helps produce a specimen that is consistent and accurate.

The EPA compliant formalin eliminates the need to constantly reference MSDS and safety sheets and takes care of all tissue specimen preservation needs.
The purpose of the Formalin Recycling System (FRS) is to recycle formalin without removing the buffered salts or altering the formalin concentration. Simply pour in dirty 10% Neutral Buffered Formalin in the top and get back clean recycled 10% Neutral Buffered Formalin at the same volume, concentration and pH at the bottom of the Formalin Formalin is the name for saturated (37%) formaldehyde solution. Thus, a protocol calling for 10% formalin is roughly equivalent to 4% formaldehyde. Beware though, that some solutions have methanol in them to stop polymerization but this could have a negative effect on your sample. Paraformaldehyde (PFA) is actually polymerized formaldehyde Neutral buffered formalin (NBF) (4% neutral buffered formaldehyde) has been advocated by most investigators as the primary fixative of choice for in situ hybridization (ISH), and specific anecdotal cautions interdicting the use of precipitating fixatives, which otherwise may offer certain advantages …
