| Bioactivity | p-Nitrophenyl phosphorylcholine (4-Nitrophenylphosphorylcholine) is a chromogenic substrate that is used to measure phospholipase C (PLC) activity. Hydrolysis of p-nitrophenylphosphorylcholine by PLC results in the liberation of p-nitrophenol, which can be measured at 405 nm at pH 7.2-7.5. |
