Competition analysis of CA 19-9 antibody [GT252] (GTX635390) (330 ng/mL) binding to immobilized recombinant HSA-CA 19-9 (coated at 3 μg/mL) in the presence of soluble Lewis^A or Lewis^X tetrasaccharides (1.0-0.01 mM). Bound antibody was detected by Goat Anti-Mouse IgG antibody (HRP) (GTX213111-01) (1:10000).

Various whole cell extracts (30 μg) were separated by 7.5% SDS-PAGE, and the membranes were blotted with CA19-9 antibody [GT252] (GTX635390) diluted at 1:1000 and competitor's antibody (MA5-12421) diluted at 1:250. The HRP-conjugated anti-mouse IgG antibody (GTX213111-01) was used to detect the primary antibody.
