Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
Enzyme-Linked Immunosorbent Assay (ELISA) is a cornerstone technique in modern biotechnology and clinical diagnostics, relying on sensitive enzyme detection systems. For assays utilizing alkaline phosphatase (AP), Disodium 4-Nitrophenyl Phosphate (PNPP) serves as an essential chromogenic substrate. Its ability to yield a colored product upon enzymatic reaction makes it indispensable for quantifying target molecules. NINGBO INNO PHARMCHEM CO.,LTD., a reputable manufacturer and supplier in China, provides high-purity PNPP (CAS 4264-83-9) to ensure the accuracy and reliability of your ELISA protocols.
The effectiveness of PNPP in ELISA lies in its well-defined enzymatic conversion. Alkaline phosphatase catalyzes the hydrolysis of PNPP, releasing p-nitrophenol, which manifests as a yellow color in alkaline solutions. This color intensity is directly proportional to the amount of alkaline phosphatase present, allowing for precise quantitative analysis. The simplicity and sensitivity of this method have made PNPP a preferred substrate for a vast array of immunoassays and biochemical tests.
For researchers and procurement managers seeking to buy Disodium 4-Nitrophenyl Phosphate, partnering with a reliable supplier is crucial. NINGBO INNO PHARMCHEM CO.,LTD. stands out as a trusted source, offering high-quality PNPP manufactured to meet stringent international standards.
