Anti-NAGA antibodies are used in the immunodetection of the protein alpha-N-acetylgalactosaminidase. In humans, the canonical protein has a reported length of 411 amino acid residues and a mass of 46.6 kDa. Its subcellular localization is in the lysosomes. It is notably widely expressed in many tissue types. A member of the Glycosyl hydrolase 27 protein family, NAGA is known to be involved with carbohydrate metabolism and homeostasis. Post-translational modifications have been described, including glycosylation. The NAGA gene has been associated with the disease, Schindler disease. Synonyms for this target antigen include GALB, Acetylgalactosaminidase, alpha-N- (alpha-galactosidase B), N-acetylgalactosaminidase, alpha-, alpha-galactosidase B, and D22S674. NAGA gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some NAGA antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
