在碱性磷酸酶测定中,采用p-对硝基苯基磷酸盐液体底物体系作为测定碱性磷酸酶活性的底物。碱性磷酸酶的底物,能够产生可在405 nm处读取的可溶性黄色终产物。使用3N NaOH可终止反应并在405 nm处读取结果。推荐用于ELISA(微孔)分析,不建议用于膜应用。应用:
对硝基苯磷酸盐(pNPP)液体底物系统将对硝基苯磷酸盐、缓冲液和所需的镁阳离子结合在一起,成为一种便捷的即用型单一溶液试剂。pNPP能够产生可溶性终产物,是碱性磷酸酶免疫测定的理想底物。
The p-Nitrophenyl Phosphate (pNPP) Liquid Substrate System combines p-nitrophenyl phosphate, buffer, and the required magnesium cations in a convenient, ready-to-use, single solution reagent. Producing a soluble end product, pNPP is the substrate of choice in alkaline phosphatase enzyme immunoassays.
Application:
p-Nitrophenyl Phosphate Liquid Substrate System has been used as a substrate to determine the activity of alkaline phosphatase in alkaline phosphatase assay.
Substrate for alkaline phosphatase that yields a soluble yellow end product that may be read at 405 nm. The reaction may be stopped with 3N NaOH and read at 405 nm. Recommended for ELISA (microwell) procedures, not recommended for membrane applications.
