This kits takes our stand-alone assay for phospholipase A1, PLA1 (A10070) and combines the necessary reagents to run 2 to 10 complete 96 well microplate assays that monitor activity in purified enzyme preparations and cell lysates. The importance of phospholipases in cellular signaling, lipid metabolism, inflammatory responses and pathological disorders related to these processes has stimulated demand for fluorescence-based activity monitoring methods. In particular the phospholipases resident in plasma and endothelium can perturb circulating LDL and HDL particles, creating pro-artherogenic forms. Recent evidence is drawing a link between these lipases and the progression of several severe neurodegenerative diseases, including Alzheimer's. Molecular Probes’ fluorogenic phospholipase A1 substrates is designed to provide continuous monitoring of phospholipase A1 (PLA1) in purified enzyme preparations, cell lysates and living cells. PLA-1 improves upon two existing reagents in two ways: first it is now PLA-1 specific and secondly it has improved the assay quality by decreasing initial background noise.
