Physicochemical properties: white or pink crystal powder. Water solubility test: 100mg / 10ml water
Purpose: biochemical research. 3,3', 5,5'- tetramethylbenzidine (TMB) is the substrate of catalase and is used for enzyme-immunoelisa reaction. The substrate can produce a soluble light yellow terminal product, which can be read by spectrophotometry at 370 or 620-650 nm The TMB reaction can be terminated with 2 m H2SO4 (the result is yellow) and can be read at 450 nm. Non carcinogenic alternatives to diaminobiphenyl.
Storage: 2 ~ 8 ℃, away from light and metal
