Description

3,3’,5,5’-Tetramethylbenzidine (TMB, CAS # 54827-17-7) is a blue chromogenic substance used in staining techniques such as immunohistochemistry.

TMB is a substrate for horseradish peroxidase. Recommended for ELISA (microwell) procedures,3,3?,5,5?-Tetramethylbenzidine has been used in a study to demonstrate that by measuring substrate absorption values off the absorption maximum, the measuring range of any immunoenzymometric assay can be extended significantly without jeopardizing assay characteristics. 3,3?,5,5?-Tetramethylbenzidine has also been used in a study to understand the formation of CuS concave superstructures with peroxidase-like activity.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

General Description

• TMB is an aromatic amine that acts as a hydrogen donor in horseradish peroxidase-catalyzed reactions
• The transfer of hydrogen results in a blue stain associated with the target of interest
• This pH-dependent color change can be confirmed using spectrophotometric methods
• TMB is commonly used in immunohistochemistry; TMB is light-sensitive, and all applications should be performed in the dark

Application

• TMB is suitable for immunohistochemistry and immunocytochemistry applications including ELISA and cell and tissue staining
