PNPP disodium (Synonyms: Para-nitrophenyl phosphate disodium)
- 目录号: TD-15928 纯度: 99.85%
| 生物活性 | PNPP (Para-nitrophenyl phosphate) disodium is a non-proteinaceous chromogenic substrate for alkaline and acid phosphatases used in ELISA and conventional spectrophotometric assays. | ||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 体外研究 (In Vitro) | Phosphatases catalyze the hydrolysis of PNPP liberating inorganic phosphate and the conjugate base of para-nitrophenol (pNP). The resulting phenolate is yellow, with a maximal absorption at 405 nm[1]. Tanda has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||||||
