Anti-St6Gal-I antibodies enable researchers to detect and measure the St6Gal-I antigen in biological samples. This target is a reported synonym of the ST6GAL1 gene, which encodes ST6 beta-galactoside alpha-2,6-sialyltransferase 1. This protein is known to function in metabolic processes, among other biological roles. The human version of St6Gal-I has a canonical amino acid length of 406 residues and a protein mass of 46.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the Golgi and is secreted of cells and notably expressed in many tissues, such as the appendix and cerebellum. Other names for this target antigen include CDw75 and SIAT1. Western Blot is the most common application for the St6Gal-I antibodies listed below. ELISA and Immunohistochemistry are also common applications.
