Phospholipase c activity
A phospholipase is an enzyme that hydrolyzes phospholipids into fatty acids and other lipophilic substances. Acids trigger the release of bound calcium from cellular stores and the consequent increase in free cytosolic Ca , an essential step in calcium signaling to regulate intracellular processes. There are four major classes, termed A, B, C, and D, which are distinguished by the type of rea… WebMar 18, 2024 · To perform the phospholipase C activity assay in a 96-well plate, based on Luberto et al. (2003), we added 40 μl of p-nitrophenylphosphorylcholine (p-NPPC, 37.5 mM, in 100 mM Tris–HCl at pH 7.4, 25% glycerol) to 60 μl of bacterial supernatant samples pre-incubated without or with liposomes (after removal of liposomes via centrifugation at ...
