Synthetic E. coli receptor of the P1 blood group antigen.

This synthetic disaccharide represents a portion of the P1 blood group antigen that is responsible for E. coli adhesion to surface membranes of the intestinal tract. Bound to Bovine Serum Albumin (BSA), it is a useful antigen for immunological studies or as an inhibitor of adhesion of endothelial cell binding to uropathogenic E. coli strains.
