Description

3,3'5,5'-Tetramethylbenzidine (TMB) is a safe-sensitive substrate used for the detection of Horseradish Peroxidase (HRP) activity. It yields a blue colour (Amax = 652nm) and changes to yellow (Amax = 450nm) upon the addition of either sulfuric or phosphoric acid. ABM’s ELISA TMB Substrate for HRP is a highly sensitive single component reagent that is ready to use for the quantitative detection of HRP bound to a solid phase or in free solution.

Concentration N/A
Application

Suitable for kinetic and endpoint assays involving Horseradish Peroxidase (HRP).

Recommended Protocol 1. Complete all required incubations with antibodies, probes and HRP labeled reagents.
2. Wash plate, at least 4 times, with phosphate buffered saline or Tris buffered saline containing 0.1% Tween-20.
3. After the final wash, shake and blot all residual buffers from plate wells.
4. Add 0.1ml of TMB Substrate for HRP to the appropriate wells and incubate 5-30 minutes.
5. (Optional Higher Sensitivity Reaction Stop) Highest sensitivity of detection is achieved by stopping the TMBHK reaction with an equal volume of 0.1ml of 0.3M of sulphuric acid. Read the more highly absorbing yellow chromogen in the stopped reaction at 450nm.
6. Assay kinetics may be monitored at 650nm as a function of time. The reaction may be stopped to preserve the blue chromogen using an equal volume of 0.1ml of 0.1% sodium fluoride or 0.15% sodium dodecyl sulfate. Measure the blue chromogen in the stopped reaction at 650nm.
Storage Condition

Store at 2-4°C and then warm up to assay temperature prior to use. ELISA TMB Substrate for HRP can also be stored at room temperature for up to 6 months. Prevent exposure to direct sunlight. Discard if solution turns blue or turbid.
