Purpose: biochemical research. Toluidine blue is one of the commonly used synthetic dyes, belonging to quinone imine dyes. Such dyes generally contain two chromophores, one is an amine group and the other is a quinone type benzene ring, to form the chromogen for color development. In addition to the chromophore, the dye should also have an atomic group that can make the chromogen have affinity for tissues and other dyed objects. The chromophore can promote the ionization of the dye to form salts, help the chromophore to produce dyeing force on the tissue, and color the tissue cells on the slice. Toluidine blue contains not only two chromophores, but also two auxiliary chromophores. It is a basic dye. The cations in toluidine blue have a dyeing effect, and the acidic substances of tissue cells are stained by combining with the cations. The nucleus can be stained to make it blue; The cytoplasm of mast cells contains heterochromatic substances such as heparin and histamine, which can show heterochromatic purplish red when encountering toluidine blue.
