Tetramethylbenzidine Usage And Synthesis |
Description | Tetramethylbenzidine(TMB) is a chromogenic substrate used in staining procedures in immunohistochemistry as well as being a visualising reagent used in enzyme-linked immunosorbent assays (ELISA). It is a white solid that forms a pale blue-green liquid in solution with ethyl acetate. TMB is degraded by sunlight and by fluorescent lights. It is a soluble chromogen substrate for horseradish peroxidase detection systems. Tetramethylbenzidine is recommended for ELISA procedures. |
Chemical Properties | Tetramethylbenzidine is a white or light yellow solid, odorless, tasteless, insoluble in water, easily soluble in acetone, ether, dimethyl sulfoxide, dimethylformamide and other organic solvents. It forms a pale blue-green liquid in solution with ethyl acetate. TMB is degraded by sunlight and by fluorescent lights. |
Uses | 3,3,5,5-Tetramethyl benzidine is used as a reagent in a sensitive staining procedure for the detection of low levels of heme-associated peroxidase activity of cytochrome P-450 on SDS-polyacrylamide or agarose gel; non-carcinogenic substitute for benzidine as reagent for the detection of blood and determination of hemoglobin content. |
Preparation | The synthesis of 3,3',5,5'-Tetramethylbenzidine involved using 2,6-dimethylaniline as the raw material. The process included activation, oxidative coupling, and purification, resulting in the production of pure material. The yield of 3,3,5,5-tetramethylbenzidine was 65%. |
Reactions | TMB can act as a hydrogen donor for the reduction of hydrogen peroxide to water by peroxidase enzymes such as horseradish peroxidase.
Shows the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) to 3,3',5,5'-tetramethylbenzidine diimine The resulting diimine causes the solution to take on a blue colour, and this colour change can be read on a spectrophotometer at the wavelengths of 370 and 650 nm. |
