Human Beta-1,4-N-Acetyl Galactosaminyl Transferase 2 (b4GALNT2) ELISA Kit

B4GALNT2 (Beta-1,4-N-Acetylgalactosaminyltransferase 2) is a Golgi-resident type II transmembrane glycosyltransferase that transfers N-acetylgalactosamine onto beta-linked galactose residues, generating the Sda/Cad blood group antigen and shaping intestinal mucin-type O-glycosylation. This Assay Genie ELISA Kit employs a human-specific antibody pair for quantitative measurement of B4GALNT2 in tissue homogenates and biological fluids, supporting research into colorectal glycosylation, norovirus host susceptibility (GII.17 strains), and Sda-negative blood group phenotypes. The kit is supplied as a complete microplate immunoassay with all reagents ready-to-use, intended for in vitro research applications and stable during refrigerated storage. Researchers studying congenital disorders of glycosylation, host-microbe interactions, or blood group antigen expression can leverage this quantitative assay to correlate B4GALNT2 levels with experimental phenotypes and patient genotypes.
