Anti-GALE antibodies are used in the immunodetection of the protein UDP-galactose-4-epimerase. In humans, the canonical protein has a reported length of 348 amino acid residues and a mass of 38.3 kDa. Up to 2 different isoforms have been reported for this protein. A member of the NAD(P)-dependent epimerase/dehydratase protein family, GALE is known to catalyze two distinct but analogous reactions: the reversible epimerization of UDP-glucose to UDP-galactose and the reversible epimerization of UDP-N-acetylglucosamine to UDP-N-acetylgalactosamine. Synonyms for this target antigen include UDP-glucose 4-epimerase, UDP galactose-4'-epimerase, UDP-GalNAc 4-epimerase, UDP-GlcNAc 4-epimerase, and SDR1E1. GALE gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of GALE antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
