title: Monoclonal IgA J539 binds galactopyranosyl antigens on its surface.
abstract: Murine monoclonal IgA J539 binds to methyl beta-D-galactopyranoside. With nearly the same affinity, it binds to methyl 6-O-pivaloyl-beta-D-galactopyranoside (4) and to methyl 6-O-beta-D-gentiobiosyl-beta-D-galactopyranoside (7). These observations confirm that the combining area of J539 is of the surface-, and not of the cavity-type.
