Description

p-Nitrophenyl Sulfate Potassium Salt is a high-purity biochemical reagent widely used as a substrate for enzyme assays. This compound is critical for research and diagnostic applications requiring precise measurement of sulfatase and phosphatase enzyme activity. It is primarily utilized by biotechnology firms, pharmaceutical R&D laboratories, and diagnostic kit manufacturers for enzymatic studies and high-throughput screening.

Application

• Enzyme Substrate for Sulfatase Assays: Used as a standard chromogenic substrate to measure arylsulfatase activity in research and clinical diagnostics.
• Phosphatase Activity Studies: Employed in biochemical research to investigate non-specific phosphatase enzymes that can hydrolyze the sulfate ester bond.
• Diagnostic Kit Manufacturing: A key component in the production of reagent kits for measuring enzyme levels in biological samples.
• High-Throughput Screening (HTS): Utilized in pharmaceutical discovery for enzyme inhibitor screening assays due to the colorimetric change upon hydrolysis.
• Biochemical Research Reagent: Serves as a model compound for studying sulfate ester hydrolysis kinetics and enzyme mechanisms.
• Quality Control in Biotechnology: Applied as a reference standard in the quality control of enzyme preparations and related bioproducts.
