Potassium Metabisulfite 2 %

artikelbilder/Artikel_11149_Kaliummetabisulfit_2.png

In histology, a 2% potassium metabisulfite solution can be used as a reducing agent in the staining of tissue specimens. One application is the removal of excess dye after staining with silver nitrate, as is the case, for example, with the Gomori trichrome stain or the silver impregnation method.

After staining with silver nitrate, the tissue can be treated with a 2% potassium metabisulfite solution to reduce excess silver nitrate and thus minimize background staining. This improves the clarity and contrast of the microscopic images and facilitates the differentiation and analysis of the various structures in the tissue.

It is important to note that potassium metabisulfite can be used at different concentrations, depending on the specific staining method and the requirements of the particular protocol.

Instructions / Protocol / Recommendations

Verwendung:

The 2% potassium metabisulfite solution is used in in vitro diagnostics in histology as a reducing agent to remove excess dye after silver nitrate staining of tissue samples. This treatment minimizes background staining, improves clarity and contrast of microscopic images, and facilitates analysis of tissue structures. The optimal concentration of potassium metabisulfite depends on the staining method used and the specific requirements of the examination protocol.

Prinzip:

Potassium metabisulfite 2% is a chemical compound used in in vitro diagnostics. When used, potassium metabisulfite binds to tissue or cell structures by reducing sulfur-containing groups, preventing oxidation of biomolecules. This process stabilizes and protects structures from oxidant damage, resulting in more accurate and reliable diagnostic results. The addition of aqua dist./VE water serves as a solvent and ensures homogeneous distribution of the active ingredients in the sample volume.
