TMB substrate kit, Pierce™
The Pierce™ TMB Substrate Kit contains soluble TMB (3,3´,5,5´-tetramethylbenzidine) that is ideal for sensitive ELISA-based applications. TMB is a chromogenic substrate for horseradish peroxidase. Once oxidised by the enzyme, this substrate yields a blue product that absorbs at 370 nm and 652 nm. Adding sulfuric or phosphoric acid to stop the reaction changes the product to yellow that absorbs at 450 nm.
Delivery information: Kit contains TMB solution (0,4 g/L), 200 ml and peroxide solution, 200 ml.
