Ready-to-use ELISA kits are available for the detection of Fucosyltransferase 1, an alias of the protein, fucosyltransferase 1 (H blood group). The official gene symbol is FUT1. The protein has a mass of 41.3 kDa and length of 365 residues. It is a member of the Glycosyltransferase 11 family and may be known by other names, including: blood group H alpha 2-fucosyltransferase, alpha(1,2)FT 1, H glycosytransferase, H glycosyltransferase, and galactoside 2-alpha-L-fucosyltransferase 1, and nonfunctional fucosyltransferase 1.
