Anti-CD77 synthase antibodies are protein reagents that detect specific antigens. The CD77 synthase antigen is another term for the human protein alpha 1,4-galactosyltransferase (P blood group), encoded by the A4GALT gene. The protein is known to catalyze the transfer of galactose from UDP-alpha-D-galactose to lactosylceramide/beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1)-ceramide(d18:1(4E)) to produce globotriaosylceramide/globoside Gb3Cer (d18:1(4E)). Canonically, it has an amino acid length of 353 residues and a mass of 40.5 kilodaltons. Its subcellular localization is in the Golgi and it is ubiquitously expressed across many tissue types. The CD77 synthase protein is a member of the Glycosyltransferase 32 protein family. Other alias names for CD77 synthase include A14GALT, A4GALT1, and Gb3S. Indicated applications for CD77 synthase antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
