Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation
Specificity / Sensitivity
cPLA2 Antibody detects endogenous levels of total cPLA2 protein. This antibody does not cross-react with the secreted PLA2 (sPLA2) or cytosolic Ca2+ independent PLA2 (iPLA2).
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the carboxy-terminal residues of human cPLA2. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from HeLa cells, untreated or TNF-α-treated (10 ng/ml for 15 minutes), and NIH/3T3 and COS cells, using Phospho-cPLA2 (Ser505) Antibody #2831 (upper) or cPLA2 Antibody (lower).
Cytosolic phospholipase A2 (cPLA2) is a ubiquitously distributed enzyme that catalyzes the hydrolysis of the sn-2 acyl bond of glycerolipids to produce lysophospholipids and release arachidonic acid (1). cPLA2 has been implicated in diverse cellular responses such as mitogenesis, differentiation, inflammation and cytotoxicity (1). Calcium binding to the amino-terminal CalB domain of cPLA2 promotes the translocation of cPLA2 from cytosol to membrane, where cPLA2 cleaves arachidonic acid from natural membrane (2). Phosphorylation of cPLA2 by MAPK (p42/44 and p38) at Ser505 (3,4) and Ser727 (5) stimulates its catalytic activity.
