Horseradish peroxidase (HRP) and HRP conjugates facilitate the ABTS oxidation in the presence of hydrogen peroxide, turning ABTS into its blue-green oxidized product. ReadiUse™ TMB Substrate Solution is a premixed solution of TMB substrate with hydrogen peroxide. It produces a blue product upon interaction with HRP or HRP conjugates without the addition of hydrogen peroxide. The soluble blue product can be quantitated at 650 nm. Use of a stop solution enhances sensitivity 2-4 fold and the resulting yellow solution can be read at 450 nm. ReadiUse™ TMB Substrate Solution provides an convenient and ultrasensitive quantitative substrate system.

Platform


Absorbance microplate reader

Recommended plateClear bottom

Example protocol


AT A GLANCE

Important
Warm ReadiUse™ TMB Solution to room temperature before use.
Note      The reagent is to be used as supplied, no dilution is required.

SAMPLE EXPERIMENTAL PROTOCOL

  1. Wash the assay plate following the incubation of HRP-labeled reagent.
  2. Add 100 µL of ReadiUse™ TMB Solution into each well.
  3. Incubate the plate at room temperature for 15 – 30 min or until the desired color develops. Note: The incubation time varies depending on the assay conditions.
  4. Measure the absorbance signal at 650 nm with an ELISA microplate reader. Note: If desired, the reaction can be stopped by adding an equal volume of 2M sulfuric acid to each well. Stopped reaction should be read at 450 nm.
