BioFX TMB Extended Range HRP Microwell Substrate - 1 L

The one component 3,3?,5,5?-tetramethylbenzidine (TMB) substrate is supplied in a ready-to-use solution. Peroxidase reacts with the TMB substrate solution to produce a soluble blue reaction product that can be read at 370 nm or 620-650 nm for ELISA applications. Stop solutions can be added to prevent further color development and reading the absorbance values at the desired wavelengths. Benefits of the BioFX� family of substrates include: Prolonged stability. Increased sensitivity. Neglibible backgrounds. Ease of Manufacturing.
