The 1x eBioscience TMB Solution is a sensitive chromogenic substrate supplied as single ready-to-use solution. TMB (3,3’,5,5’-Tetramethylbenzidine) is a substrate for horseradish peroxidase (HRP) and is recommended for Ready-SET-Go! ELISA kits.
During the enzymatic reaction the TMB substrate will result in a blue color that can be read on a spectrophotometer at 650 nm. This kinetic reaction can be stopped using 1M phosphoric acid resulting in a color change to yellow that can be read at 450 nm.
