Colorimetric, chemiluminescent and chemifluorescent substrates for alkaline phosphatase (AP), horseradish peroxidase (HRP) and other enzyme reporter systems; includes several sensitive formulations of TMB for kinetic, competition or sandwich ELISA.
Thermo Scientific™ Pierce TMB ELISA Substrates detect horseradish peroxidase (HRP) activity, yielding a blue color (Amax = 370 nm and 652 nm) that changes to yellow (Amax = 450 nm) upon addition of a sulfuric or phosphoric acid stop solution.
