Representative array images illustrating specific glycan recognition. Antibodies were incubated on the array and binding was detected with Cy3-labeled goat anti-mouse Ig. Each array component was printed in duplicate, resulting in pairs of spots. Control spots, Cy3-labeled BSA, are marked with a ‡. A) Antibody L14C6, which preferentially binds LeA and LeX; B) Antibody L7C4, which preferentially binds BG-A, BG-A1, and glycoproteins displaying blood group A; C) Antibody L9G10A, which binds BG-H2 and maltose.
