Clone M021 detects a 38 kDa* protein corresponding to the molecular mass of Annexin A1 on SDS-PAGE immunoblots of human A431, MDA-MB-231, and A549. The antibody also detects full length recombinant human Annexin A1, but not Annexin A2 or Annexin A5 recombinant proteins. The antibody works for western blot, ELISA, immunocytochemical labeling, and immunoprecipitation.
Annexin I belongs to a family of Ca (2+) -dependent phospholipid binding proteins that are preferentially located on the cytosolic face of the plasma membrane. Annexin I has a molecular mass of 40 kDa, with phospholipase A2 inhibitory activity. Since phospholipase A2 is required for the biosynthesis of the potent mediators of inflammation, prostaglandins and leukotrienes, annexin I may have potential anti-inflammatory activity.
