The Les ELISA kits listed below utilize specific antibodies for the plate-based assay of Les in various samples. Les is another term for the FUT3 gene, which encodes the protein, fucosyltransferase 3 (Lewis blood group) in humans. It has been reported that Les plays a role in the regulation of cell proliferation, among other functions. Structurally, the FUT3 protein is described to be 361 amino acid residues in length and 42.1 kilodaltons in mass. It is localized to the golgi of the cell. In terms of tissue specificity, it is reported to be highly expressed in stomach, colon, small intestine, lung and kidney and to a lesser extent in salivary gland, bladder, uterus and liver. This protein is known to be glycosylated. Other names for this target antigen include CD174, CD174, and FT3B.
