Bio-Rad, BUF056A, TMB Core

TMB CORE is a high performance TMB (3,3´, 5, 5´- tetramethylbenzidine) solution, recommended for use in ELISA detection systems as a substrate for horseradish peroxidase (HRP). TMB CORE contains TMB, substrate buffer and hydrogen peroxide in a safe, ready to use solution. TMB CORE produces a deep blue color during the enzymatic degradation of H 2 O 2 by horseradish peroxidase. For kinetic assays the absorbance is read at 655nm (blue). However, for endpoint assays the reaction may be stopped with 0.2M sulphuric acid, resulting in a yellow colour read at 450nm.
