Detection of Human PLA2G2A by Western Blot. Western blot shows lysates of human spleen tissue. PVDF Membrane was probed with 2 µg/mL of Human PLA2G2A Monoclonal Antibody (Catalog # MAB5374) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for PLA2G2A at approximately 17 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.

Phospholipase A2 Group IIA (PLA2G2A) is a 17 kDa member of the phospholipase A2 family of enzymes that hydrolyzes the sn-2 ester bond of phospholipids. Human PLA2G2A is synthesized as a 144 amino acid (aa) precursor that contains a 20 aa signal sequence and a 124 aa mature chain. Mature human PLA2G2A shares 72%, 68%, and 60% aa sequence identity with mature rat, mouse, and bovine PLA2G2A, respectively. PLA2G2A is a calcium dependent phospholipase expressed in many cell types associated with inflammation, including platelets, neutrophils, and mast cells. Most secretory PLA2s are stored in cytoplasmic granules and are released into the extracellular environment on appropriate cell activation. Thus, they are present at higher concentrations in the plasma and biologic fluids of patients with systemic inflammatory, autoimmune, or allergic diseases.
