Anti-MGAM antibodies are used in the immunodetection of the protein maltase-glucoamylase. In humans, the canonical protein has a reported length of 2753 amino acid residues and a mass of 312 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the Glycosyl hydrolase 31 protein family, Mgam is known to be an alpha-(1,4) exo-glucosidase involved in breakdown of dietary starch oligosaccharides in small intestine. Synonyms for this target antigen include MGA, alpha-1,4-glucosidase, brush border hydrolase, maltase-glucoamylase (alpha-glucosidase), maltase-glucoamylase, intestinal, and MG. MGAM gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some Mgam antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
