Anti-ST3GALII antibodies enable researchers to detect and measure the ST3GALII antigen in biological samples. This target is a reported synonym of the ST3GAL2 gene, which encodes ST3 beta-galactoside alpha-2,3-sialyltransferase 2. This protein is known to function in protein glycosylation, among other biological roles. The human version of ST3GALII has a canonical amino acid length of 350 residues and a protein mass of 40.2 kilodaltons. It is reported to be localized in the Golgi and is secreted of cells and widely expressed in many tissue types. ST3GALII is a member of the Glycosyltransferase 29 protein family.
