A staple reagent in organic synthesis and formulation chemistry, Roti ® Fair Pnpp 20Mg is a valuable substrate solution for alkaline phosphatase detection. This product comes in the form of pre-weighed tablets, facilitating rapid and convenient preparation of the solution. The resulting solution can be filtered (0.22 µm) for sterilization before storage at -20 °C. Each tablet contains 20 mg of pNPP, which when dissolved yields an end concentration of 1 mg/ml. The solution exhibits a yellow color upon reaction with alkaline phosphatase, making it suitable for various applications such as ELISA and activity assays.
