ELISA Substrates and Reagents
Thermo Scientific™ 1-Step™ TMB ELISA Substrate Solutions
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.
Thermo Scientific™ Pierce™ Diethanolamine Substrate Buffer (5X)
Optimized, reliable and convenient stock solutions of peroxide for HRP-based assays and diethanolamine for alkaline phosphatase (alk-phos) detection.
Thermo Scientific™ 1-Step™ ABTS Substrate Solution
Ready-to-use, water-soluble peroxidase substrate tablets that yield a measurable green end-product for use in ELISA methods.
Invitrogen™ ELISA Buffer Kit
Concentrated
Thermo Scientific™ OPD Substrate Tablets (o-phenylenediamine dihydrochloride)
Water-soluble horseradish peroxidase (HRP) substrate that produces a yellow-orange product detectable at 492nm by ELISA plate readers.
Thermo Scientific™ ONPG (o-nitrophenyl-β-D-galactopyranoside)
Preferred colorimetric beta-galactosidase (b-Gal) substrate for ELISA applications.
Invitrogen™ Assay Buffer (10X)
Used in immunoassays and in Western and Southern blotting for alkaline phosphatase Tropix™ substrate conjugates.
Invitrogen™ CDP-Star™ Substrate (0.4 mM Ready-to-Use) with Enhancer
