Anti-angiopoietin like 2 antibodies are used for the immunodetection of the protein encoded by the ANGPTL2 gene. In humans, the canonical protein has a reported length of 493 amino acid residues and a mass of 57.1 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 2 different isoforms for this protein. It is found to be widely expressed in the heart, small intestine, spleen and stomach. It is noted to be involved in cell to cell signaling. Post-translational modifications have been described, including N-glycosylation. Other names for this target antigen include ARP2 and HARP. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of angiopoietin like 2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
