Proveedor: SIGMA ALDRICH MICROSCOPY

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: Reagent for aluminium. Aurintricarboxylic acid readily polymerises in aqueous solution, forming a stable free radical that inhibits protein-nucleic acid interactions. It is a potent inhibitor of ribonuclease and topoisomerase II by preventing the binding of the nucleic acid to the enzyme. It stimulates tyrosine phosphorylation processes including the Jak2/STAT5 pathway in NB2 lymphoma cells, ErbB4 in neuroblastoma cells, and MAP kinases, Shc proteins, phosphatidylinositide 3-kinase and phospholipase C in PC12 cells. Aurintricarboxylic acid inhibits apoptosis in many cell types. Its neuroprotective effect, perhaps due to its ability to prevent down-regulation of Ca²⁺ impermeable GluR2 receptors or to its ability to inhibit calpain, a Ca²⁺-activated protease that is activated during apoptosis.
