Gal1-β-4GlcNAc1-β-6Gal is a biochemical reagent used in glycoscience research. Glycoscience examines the structure, synthesis, biology, and evolution of sugars. It encompasses carbohydrate chemistry, glycoconjugate formation and degradation enzymology, protein-glycan recognition, and the roles of glycans in biological systems. This field is closely linked to fundamental research, biomedicine, and biotechnology.
