A Blood Group H Type III trisaccharide ligand equipped with a biotin tag. The biotin moiety binds with high affinity to streptavidin and neutravidin, enabling straightforward immobilization on chips, in wells, or on other streptavidin/neutravidin-coated platforms. This compound presents the Blood Group H Type III trisaccharide, a histo-blood group antigen variant. It is a ligand for H-antigen-recognizing lectins and a probe for blood group and host-pathogen interaction studies.
