TMB is a substrate and chromogen that yields a blue color when oxidized, as a result of oxygen radicals produced by the reduction of hydrogen peroxide by HRP. For kinetic or non-stopped ELISA assays, the TMB chromogen has maximal absorbances at 370 nm and 652 nm. The color then changes to yellow with the addition of sulfuric or phosphoric acid, with maximum absorbance at 450 nm.


 

One-component, Ready-to-use TMB Formulation Simplifies ELISA Kits

The MaxSignal® TMB (3,3’,5,5’ – tetramethylbenzidine) Microwell Substrate Solution is a one-component, ready-to-use liquid formulation that requires no preparation before use. This simplifies ELISA kits for the end user while increasing accuracy by reducing potential errors. Unlike most other commercially available substrates, these products contain no DMF or DMSO.


 

TMB Validated in Hundreds of Different Types of ELISA Kits

The MaxSignal TMB Microwell Substrate Solution is a proven, robust solution that has been incorporated into hundreds of different types of ELISA kits developed for both the research and applied markets which have been sold throughout the world for many years. This substrate solution provides high signal and high sensitivity for ELISA kits.


 

TMB Offers a Long Shelf Life – Stable for 3 years at 2 - 8ºC

The MaxSignal TMB Microwell Substrate Solution has a shelf life of 3 years when stored at 2-8°C. This reagent has undergone rigorous stability testing to measure both its stability and performance over a prolonged period of time. Stability tests were conducted with the MaxSignal TMB Microwell Substrate Solution along with TMB obtained from other leading manufacturers. As seen in the figures below, the MaxSignal TMB Microwell Substrate Solution is more stable than competitors’ TMB when tested for 300 days at room temperature, 4°C and 37°C. This increased stability translates to increased kit stability for ELISA kit manufacturers.
