Enzymatic Assay for the Quantitative Determination of Phospholipase A1 or A2 Activity in a Sample

摘要

The invention relates to a new method for measuring a calcium-dependent phospholipase A1 or A2 enzymatic activity in a sample, comprising the following steps: a) contacting said sample with a solid phase coated with a fluorochrome-labelled phospholipase A1 or A2 substrate, wherein the molecular coverage is in the range 8 to 30 fluorochrome-labelled phospholipase A1 or A2 substrate molecules/nm2 in conditions where calcium-dependent phospholipase A1 or A2 enzymatic activity is blocked. b) reading the fluorescence emission overtime c) adding a solution to initiate calcium-dependent phospholipase A1 or A2 enzymatic activity d) reading the fluorescence emission overtime, and kits for carrying out said method.
