Toluidine Blue Staining Kit,1%,Phosphate Buffer Method

Toluidine Blue O is a commonly used synthetic dye belonging to the quinone-imine dye class. These dyes mainly contain two chromophores—amino groups and quinoid benzene rings—which contribute to color development. The cations in toluidine blue are responsible for staining, as they bind to acidic substances in tissue cells. Toluidine blue also contains two auxochromes that promote ionization and salt formation, enhancing the dye’s affinity for tissues and enabling cellular staining. It can stain nuclei blue. Additionally, mast cells contain metachromatic substances such as heparin and histamine, which stain metachromatically purple-red when exposed to toluidine blue.EnkiLife Toluidine Blue O Stain (1%, Phosphate Buffer Method) is commonly used for staining cells and mast cells.
