Anti-ABCG1 antibodies are used in the immunodetection of the protein ATP binding cassette subfamily G member 1. In humans, the canonical protein has a reported length of 678 amino acid residues and a mass of 75.6 kDa. Its subcellular localization is in the ER, Golgi, and cell membrane. Up to 8 different isoforms have been reported for this protein. It is reported to be expressed in several tissues. A member of the ABCG protein family, ABCG1 is known to catalyze the efflux of phospholipids such as sphingomyelin, cholesterol and its oxygenated derivatives like 7beta-hydroxycholesterol and this transport is coupled to hydrolysis of ATP. Synonyms for this target antigen include WHITE1, ABC transporter 8, ATP-binding cassette transporter 8, ATP-binding cassette transporter member 1 of subfamily G, and ABC8. ABCG1 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Over 230 citations in the literature describe the use of ABCG1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
