Tmb wavelength
3,3′,5,5′-Tetramethylbenzidine or 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). TMB is a white solid that forms a pale blue-green liquid in solution with ethyl acetate. TMB is degraded … See more TMB can act as a hydrogen donor for the reduction of hydrogen peroxide to water by peroxidase enzymes such as horseradish peroxidase. The resulting one-electron oxidation product is a See more TMB should be kept out of direct sunlight as it is photosensitive. It is not known if TMB is carcinogenic and the evidence is contradictory: TMB is not mutagenic by the See more WebThe specific colors obtained with particular enzyme-chromophore systems at specific wavelengths in spectrophotometers reading.

WebKinetic Assays: The TMB substrate produces a blue color upon reaction with peroxidase. Read at a wavelength of 620 - 650 nm. Endpoint Assays: The addition of 100 µL (or an equal volume) of stop solution to the microwell plate will halt color development and will turn the TMB substrate yellow. Read at a wavelength of 450 nm. Webproducts are: TMB (dual function substrate), ABTS (2,2'-azino-di [3-ethylbenzthiazoline] sulfonate), and OPD o-phenylenediamine). TMB is a highly sensitive substrate. Due to its rapid reaction rate, it is ideally suited for on-line kinetic analysis. It produces a blue color measurable at a wavelength of 650 nm. TMB can also
WebThen TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm. The concentration of target in the samples is then determined by comparing the OD of the samples to the standard curve.
