these data and the results of mild oxidation of the antigen with sodium periodate suggest that the epitope recognized by antibody a2b5 contains the trisialyl structure found in gt3 but does not include the polyalcohol chain of the terminal sialic acid which can be oxidized by periodate or acetylated without modifying the affinity for the antibody .
