Ready-to-use, water-soluble peroxidase substrate tablets that yield a measurable green end-product for use in ELISA methods.

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.

Water-soluble horseradish peroxidase (HRP) substrate that produces a yellow-orange product detectable at 492nm by ELISA plate readers.

HRP substrate optimized to generate an intense light signal and provide exception performance in luminometer-based assays.

Preferred colorimetric beta-galactosidase (b-Gal) substrate for ELISA applications.

Optimized, reliable and convenient stock solutions of peroxide for HRP-based assays and diethanolamine for alkaline phosphatase (alk-phos) detection.

Thermo Scientific™ Pierce PNPP Substrates are powders, tablets, solutions and complete kits of p-nitrophenyl phosphate, a colorimetric, soluble substrate of alkaline phosphatase for use in ELISA applications.

Optimized, reliable and convenient stock solutions of peroxide for HRP-based assays and diethanolamine for alkaline phosphatase (alk-phos) detection.

Water-soluble horseradish peroxidase (HRP) substrate that produces a yellow-orange product detectable at 492nm by ELISA plate readers.

Conduct stopped, non-stopped and kinetic assays using this soluble fluorogenic (chemifluorescent) peroxidase substrate for ELISA.

Conduct stopped, non-stopped and kinetic assays using this soluble fluorogenic (chemifluorescent) peroxidase substrate for ELISA.

HRP substrate formulated for superior protein detection and low-end linearity in chemiluminescent ELISA applications.

Enable sensitivity comparable to enhanced chemiluminescence (ECL) using the most sensitive fluorescent ELISA substrate for peroxidase (HRP).

For use in BD OptEIA™ ELISA sets. Substrate Reagent A, which is clear and colorless, contains hydrogen peroxide. Substrate Reagent B is colorless to a very light amber solution containing 3,3', 5,5' tetramethylbenzidine (TMB) in an organic solvent.
