Description

Pyridoxal Phosphate-6-Azophenyl-2'-Sulfonic Acid is a chemically modified derivative of pyridoxal phosphate (PLP), the active form of vitamin B6, designed for specific biochemical applications. This compound is valued for its role as a versatile chemical probe and reagent in enzyme research and diagnostic assay development. It is primarily utilized by researchers and manufacturers in the life sciences, pharmaceutical, and diagnostic industries for studying PLP-dependent enzymes and developing sensitive detection systems.

Application

• Biochemical Research Probe: Used as an active-site directed inhibitor or affinity label for pyridoxal phosphate-dependent enzymes, such as transaminases and decarboxylases.
• Diagnostic Assay Development: Serves as a key reagent in the development of enzyme-linked immunosorbent assays (ELISAs) and other immunoassays for clinical diagnostics.
• Enzyme Activity Studies: Employed to investigate enzyme kinetics, mechanism, and cofactor binding interactions in academic and industrial research settings.
• Protein Conjugation & Labeling: Acts as a hapten for the production of specific antibodies or as a labeling agent for proteins in bioconjugation chemistry.
• Pharmaceutical Intermediate: Potential use as a specialized intermediate in the synthesis of novel pharmaceutical compounds targeting metabolic pathways.
