Anti-FABP1 antibodies are used in the immunodetection of the protein fatty acid binding protein 1. In humans, the canonical protein has a reported length of 127 amino acid residues and a mass of 14.2 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the liver, kidney, duodenum, colon, and appendix. A member of the Fatty-acid binding protein (FABP) protein family, FABP1 is reported to play a role in lipoprotein-mediated cholesterol uptake in hepatocytes. Synonyms for this target antigen include L-FABP, fatty acid-binding protein, liver, fatty acid binding protein 1, liver, liver-type fatty acid-binding protein, and FABPL. FABP1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 80 citations in the literature describe the use of FABP1 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
