Application

Tetramethylbenzidine is a novel and safe chromogenic reagent; TMB has gradually replaced the strong carcinogen benzidine and other carcinogenic benzidine derivatives, and is applied in clinical laboratory testing, forensic examination, criminal investigation, and environmental monitoring; Especially in clinical biochemical testing, TMB, as a new substrate for peroxidase, has been widely used in enzyme immunoassay (EIA) and enzyme-linked immunosorbent assay (ELISA)
