Anti-apolipoprotein F antibodies are used for the immunodetection of the protein encoded by the APOF gene. In humans, the canonical protein has a reported length of 326 amino acid residues and a mass of 35.4 kDa. It is known to be a secreted protein. It is notably expressed by the liver and secreted in plasma. A member of the Apolipoprotein F protein family, it is reported to be a minor apolipoprotein that associates with LDL. Post-translational modifications have been described, including O-glycosylation. Other names for this target antigen include LTIP and lipid transfer inhibitor protein. Gene orthologs have been identified in the mouse, rat, frog, zebrafish, chimpanzee and chicken species. Some apolipoprotein F 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.
