Anti-ST6GALNAC1 antibodies are used in the immunodetection of the protein ST6 N-acetylgalactosaminide alpha-2,6-sialyltransferase 1. In humans, the canonical protein has a reported length of 600 amino acid residues and a mass of 68.6 kDa. Its subcellular localization is in the Golgi. It is notably expressed in many tissues, such as the appendix and bronchus. A member of the Glycosyltransferase 29 protein family, ST6GALNAC1 is known to be involved with protein glycosylation. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include GalNAc alpha-2, 6-sialyltransferase I, long form, SIAT7-A, ST6 (alpha-N-acetyl-neuraminyl-2,3-beta-galactosyl-1,3)-N-acetylgalactosaminide alpha-2,6-sialyltransferase 1, and alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase 1. ST6GALNAC1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of ST6GALNAC1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
