Anti-amylase alpha 2B antibodies are used for the immunodetection of the protein encoded by the AMY2B gene. In humans, the canonical protein has a reported length of 511 amino acid residues and a mass of 57.7 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Glycosyl hydrolase 13 protein family, it is known to be involved with carbohydrate metabolism and homeostasis. Other names for this target antigen include AMY3, HXA, alpha-amylase 2B, 1,4-alpha-D-glucan glucanohydrolase 2B, amylase alpha 2B (pancreatic), and AMY2. Gene orthologs have been identified in the mouse, rat and chimpanzee species.
