Anti-APOA2 antibodies are used in the immunodetection of the protein apolipoprotein A2. In humans, the canonical protein has a reported length of 100 amino acid residues and a mass of 11.2 kDa. It has been described to be a secreted protein. A member of the Apolipoprotein A2 protein family, APOA2 is believed to stabilize HDL (high density lipoprotein) structure by its association with lipids, and affect the HDL metabolism. Post-translational modifications have been described, including O-glycosylation and phosphorylation. Synonyms for this target antigen include ApoA-II, apoAII, apolipoprotein A-II, and Apo-AII. APOA2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some APOA2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
