C47H48N3NaO7S2=854.02

Grade: high purity grade

EM(595nm,H2O)：＞36300

Biological staining test: qualified

Physicochemical properties: dark blue purple brown crystal powder. Soluble in ethanol and hot water, bright blue, slightly soluble in cold water. It turns blood red with concentrated sulfuric acid, turns orange red after dilution, and turns purple when sodium hydroxide is added to the aqueous solution. Water solubility: 40 g / L (20 ℃). The maximum absorption wavelength is 610nm. Irritating

Purpose: biochemical research. Used for gel electrophoresis and protein staining. It is 3 times more sensitive than naphthol blue black B1 without penetrating into the gel, which is simple and sensitive; It can detect various proteins, and the chemical substances and free amino acids involved in Laurie reaction have no effect on the protein staining detection. It is also a P2X7 purinergic receptor agonist
