Product Information

• Name: N-(3-Sulfopropyl)-3,3',5,5'-tetramethylbenzidine sodium
• Synonyms: TMBZ-PS4-Amino-4'-sulfopropylamino-3,3',5,5'-tetramethylbiphenyl sodium saltSodium 3-((4'-amino-3,3',5,5'-tetramethyl-[1,1'-biphen yl]-4-yl)amino)propane-1-sulfonate
• Brand: Biosynth
• Description: N-(3-Sulfopropyl)-3,3',5,5'-tetramethylbenzidine (TMB) sodium salt is a highly sensitive chromogenic substrate used for the detection and quantification of peroxidase enzyme activity. This water-soluble substrate undergoes a color change from colorless to blue upon oxidation by peroxidase enzymes in the presence of hydrogen peroxide. The reaction can be stopped by adding an acid, resulting in a yellow color that can be measured spectrophotometrically. TMB sodium salt is widely used in various applications, including enzyme-linked immunosorbent assays (ELISA), immunohistochemistry, and other diagnostic tests, due to its high sensitivity, low background signal, and excellent stability.
