Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
In the realm of biochemical research and diagnostics, the quality of reagents directly impacts the reliability of experimental outcomes. Disodium 4-Nitrophenyl Phosphate (PNPP) is a widely utilized substrate in assays involving phosphatases, most notably alkaline phosphatase (AP). Its function as a chromogenic indicator makes it invaluable for quantifying enzyme activity. For scientists and procurement professionals seeking a dependable source for this critical chemical, understanding its applications and sourcing from reputable manufacturers is key.
PNPP, with its CAS number 4264-83-9, serves as an excellent substrate for alkaline phosphatase. When acted upon by AP, it liberates p-nitrophenol, which is yellow in solution and can be easily measured using spectrophotometry. This straightforward detection mechanism makes it a popular choice for a wide range of applications, including enzyme-linked immunosorbent assays (ELISA), Western blotting, and various enzymatic activity assays. The ability to perform both kinetic and endpoint determinations further enhances its utility.
