3,3",5,5"-Tetramethylbenzidine, 98%
化学性质
应用
Excellent colorimetric substrate for detection of horseradish peroxidase labelled probes; particularly useful in ELISA techniques, blue result can be read spectrophotometrically at 370 or 650 nm3,3",5,5"-Tetramethylbenzidine is used as a clinical reagent for testing blood. It is also a chromogenic substrate which is used in staining procedures in immunohistochemistry. Further, it is used as a visualizing reagent in enzyme-linked immunosorbent assays. In addition to this, it is used as a replacement for carcinogenic compounds such as benzidine and o-phenylenediamine.
