WebEach Sigma FAST pNPP tablet set yields a solution containing 1.0 mg/ml pNPP, 0.2 M Tris buffer. EIA applications using pNPP may be read in timed assays or stopped with 3N NaOH for delayed readings. SIGMA FAST™ require only the addition of distilled or deionized water to prepare an active substrate solution. Tablets are individually packaged ... WebPrepare a series of assay mixtures such that the concentrations of P i and pNPP will correspond to those given below after addition of the enzyme containing solution: • [P i] = 0,0.2, 0.5, 1.0, 2.0 mM [pNPP] = 1.0mM in all solutions • [P i] = 0,0.2, 0.5, 1.0, 2.0 mM [pNPP] = 2.5mM in all solutions

WebThe second procedure required a protein assay to determine the activity of acid phosphatase. The artificial substrate p-nitrophenylphosphate (PNPP) can be used to measure acid phosphatase activity in the unknown mystery mix. Acid phosphatase produces p-nitrophenol (PNP) from PNPP and the resulting product produces a Webp-Nitrophenyl Phosphate (PNPP) is a non-proteinaceous, non-specific substrate used to assay protein, alkaline and acid phosphatases. The PNPP phosphatase activity is … nier replicant faith weapon
