Anti-B4GALNT2 antibodies are used in the immunodetection of the protein beta-1,4-N-acetyl-galactosaminyltransferase 2. In humans, the canonical protein has a reported length of 566 amino acid residues and a mass of 63.3 kDa. Its subcellular localization is in the Golgi. Up to 3 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the Glycosyltransferase 2 protein family, B4GALNT2 is reported to be involved in synthesis of the Sd(a) antigen (Sia-alpha2,3-[GalNAc-beta1,4]Gal-beta1,4-GlcNAc), a carbohydrate determinant expressed on erythrocytes, the colonic mucosa and other tissues. The B4GALNT2 gene has been associated with the disease, Sd(a) polyagglutination syndrome. Synonyms for this target antigen include UDP-GalNAc:Neu5Acalpha2-3Galbeta-R beta1,4-N-acetylgalactosaminyltransferase, beta 1,4 N-acetylgalactosaminyltransferase/betal,4 GalNAcT/Sda-GalNAcT, and UDP-GalNAc:Neu5Aca2-3Galb-R b1,4-N-acetylgalactosaminyltransferase. A number of B4GALNT2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
