Sigma Aldrich Fine Chemicals Biosciences SIGMAFAST™ OPD | 5 sets
SIGMAFAST™ OPD (o-Phenylenediamine dihydrochloride) tablets have been developed for use as a soluble substrate for the detection of peroxidase activity in enzyme immunoassays (EIA). OPD is the EIA substrate of choice as it exhibits high sensitivity. EIA applications utilizing OPD may be read in timed assays or stopped with dilute acid solutions for delayed readings.
Sigma Aldrich Fine Chemicals Biosciences 3,3',5,5'-TETRAMETHYLBENZIDINE
3,3',5,5'-Tetramethylbenzidine (TMB) Liquid Substrate System
Neogen Diagnostics Custom TMB Substrate, 200 ML, HRP, Microwell, Colorimetric
Custom TMB Substrate is a one bottle stabilized chromogenic substrate for use with horseradish peroxidase (HRP) immunoassays. It contains both 3,3,5,5 tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2). Custom TMB Substrate develops a deep blue color in the presence of peroxidase labelled conjugate. This substrate has been optimized for use with microwell assays, especially ELISA. Custom TMB is not for use with assays requiring a precipitating substrate. Stable for a minimum of 36-months when stored at 2-8C.

Rockland Immunochemicals TMB ELISA PEROXIDASE SUBSTRATE - TMBE-1000
TMB ELISA Peroxidase Substrate (3, 3', 5, 5' - Tetramethylbenzidine) is a chromogenic substrate used to visualize antibody reactivity in ELISA experiments. In the presence of peroxidases, TMB can act as an electron donor for the conversion of peroxides to water, changing the color of solution to a blue color equivalent to the degree of reactivity. This reaction can be halted with acid to change the TMB to yellow. TMB ELISA Peroxidase Substrate is ideal for investigators in Microbiology, Immunology, and Cancer research.

Seracare Life Sciences Inc ABTS 2-C ELISA HRP SUBSTRATE
A good, all-purpose substrate that offers the widest working range. Ideal when low background is required and moderate sensitivity is acceptable. ABTS develops a blue-green color in the presence of peroxidase labeled conjugates measurable between 405 and 410 nm. No change in color when reaction is stopped. Recommended for ELISA applications. Two-component format that contains 2, 2'-azino-di(3-ethylbenzthiazoline-6-sulfonate), simply mix and use. Has longer shelf life than single component format.
