An easy to use two step kit that reduces melanin while preserving delicate tissue, cytologic detail, and antigens. Heavy melanin pigment in the cells can obscure cellular morphology and subsequently impair interpretation when using routine or special histochemical stains. The melanin bleach kit enables the removal of melanin from tissue sections allowing for positive staining to be interpreted correctly. A two step kit that does not require mixing. Used before staining to reduce melanin while preserving delicate tissue, cytologic detail, and antigens.

Methyl green is a synthetic, triphenylmethane-type cationic dye related to ethyl green mainly used as DNA stain in histochemistry. It possesses aniline rings with different degrees of methylation. The dye binds specifically to the A-T rich regions of the major groove of DNA with the help of two positive charges. Methyl green in combination with pyronin is extensively used to stain RNA and plasma cells in tissue sections and cytologic preparations.

Silver nitrate along with iodine are among several inorganic substances used to induce colour in microscopical preparations. Silver nitrate as a biological stain exploits the strong colors of colloidal metallic silver. Silver nitrate is an important component of the silver staining that is used for the detection of proteins separated by polyacrylamide gel electrophoresis. Silver nitrate is a component of the silver stain kit. It is required for image development in diamine as well as non-diamine silver staining.
