Anti-LCAT antibodies are used in the immunodetection of the protein lecithin-cholesterol acyltransferase. In humans, the canonical protein has a reported length of 440 amino acid residues and a mass of 49.6 kDa. It has been described to be a secreted protein. It is notably expressed in blood plasma. A member of the Lipase protein family, LCAT is known to be involved with cholesterol metabolism and homeostasis and the metabolism of lipids. Post-translational modifications have been described, including O-glycosylation and N-glycosylation. Synonyms for this target antigen include 1-alkyl-2-acetylglycerophosphocholine esterase, PAF acetylhydrolase, phosphatidylcholine--sterol O-acyltransferase, and phosphatidylcholine-sterol acyltransferase. LCAT gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of LCAT 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.
