Stop Solutions for TMB

Our Stop Solutions are acid-based solutions for use with our TMB ELISA substrates. TMB reacts with peroxide in the presence of horseradish peroxidase to produce a soluble blue product. This reaction can be stopped by the addition of an equal amount of stop solution, resulting in a soluble yellow product that can be read at 450nm.

Supplied in liquid format. For general use to stop colour development in ELISA.
