Descripción: 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.

Descripción: 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.

Descripción: Wright′s Stain solution is commercially available and is generally used in hematology. Its preparation involves heating methylene blue with sodium bicarbonate and combining the mixture with eosin. It is alkaline, hence, its concentration is continuously changing due to the progressive oxidizing action of the alkali. Therefore, Giemsa′s stain is added to preserve the azurophilic properties of polychrome dyes.
