Anti-CETP antibodies are used in the immunodetection of the protein cholesteryl ester transfer protein. In humans, the canonical protein has a reported length of 493 amino acid residues and a mass of 54.8 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. It is notably expressed by the liver and secreted in plasma. A member of the BPI/LBP protein family, CETP is reported to be involved in transfer of neutral lipids, including cholesteryl ester and triglyceride, among lipoprotein particles. Synonyms for this target antigen include HDLCQ10, BPI fold containing family F, cholesteryl ester transfer protein plasma, lipid transfer protein I, and BPIFF. CETP gene orthologs have been reported in the frog, zebrafish, chimpanzee and chicken species. A number of CETP antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
