Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation,

Specificity / Sensitivity

Phospho-cPLA2 (Ser505) Antibody detects endogenous levels of cPLA2 only when phosphorylated at serine 505. It 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 phosphopeptide corresponding to residues surrounding Ser505 of human cPLA2. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

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 (upper) or cPLA2 Antibody #2832 (lower).

对HeLa细胞,未处理或10 ng/ml TNF-α处理15分钟,以及NIG/3T3和COS细胞,使用Phospho-cPLA2 (Ser505)抗体(上图)或cPLA2抗体#2832(下图)进行Western blot分析。


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.
