BioFX™ brand range of substrate solutions  

BBI offers the  BioFX™ brand range of substrate solutions, designed primarily for use in IVD applications, to our EU clients. The range has ready to use substrate solutions for both Horse Radish Peroxidase and Alkaline Phosphatase enzyme, complimenting the BBI manufactured enzyme products. 

The BioFX™ TMB family has a broad range of kinetic rates with low background and improved signal‐to‐noise ratios that improve assay performance.  The BioFX® TMB One Component HRP Microwell Substrate contains 3,3’,5,5’‐tetramethylbenzidine (TMB) and is supplied as a ready‐to‐use solution.  Peroxidase reacts with the 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 colour development and reading the absorbance values at the desired wavelengths.  

BioFX™ alkaline phosphatase substrates contain p‐nitrophenylphosphate (p‐NPP) and are supplied as formulated solutions for immunoassay applications.  A soluble yellow product is obtained when this substrate is reacted with alkaline phosphatase.
