207738-08-7 - Introduction
A substrate for catalase, used in enzyme-free ELISA reactions. The substrate can produce a soluble light yellow end product, which can be photometrically read at 370 or 620-650 nm. The TMB reaction can be terminated with 2 M H2SO4 (the result is yellow) and can be read at 450 nm. Non-carcinogenic substitutes for diaminobiphenyl. CAS number: 64285-73-0 (anhydrous) CAS number: 207738-08-7 (hydrate)
