Ready-to-use ELISA kits are available for the detection of beta-1,4-GalT, an alias of the protein, beta-1,4-galactosyltransferase 1. The official gene symbol is B4GALT1. The protein, with a mass of 43.9 kDa and length of 398 residues, is reported to be membrane-associated and secreted. It is a member of the Glycosyltransferase 7 family and may be known by other names, including: beta-N-acetylglucosaminylglycopeptide beta-1,4-galactosyltransferase, beta-N-acetylglucosaminyl-glycolipid beta-1,4-galactosyltransferase, UDP-galactose:beta-N-acetylglucosamine beta-1,4-galactosyltransferase 1, UDP-Gal:betaGlcNAc beta 1,4- galactosyltransferase polypeptide 1, and N-acetyllactosamine synthase, and lactose synthase.
