The substrate produces a soluble end product that is pale blue in color and can be read spectrophotometrically at 370 or 620-650 nm. The TMB reaction may be stopped with 2 M H2SO4 (resulting in a yellow color), and read at 450 nm. A sensitive and specific reagent for the detection of blood, assay of hemoglobin, assay of peroxidases.Quality Level: PREMIUMAssay: ≥98.0% (NT)MP: 166-171 °C; 168-171 °C(lit.)Storage Temp.: 2-8°C
