title: Monoclonal antibodies against the GP-2 subunit of laminin.
abstract: Two stable rat X mouse hybridoma lines have been isolated. These hybridoma lines produce IgG antibodies directed against the polypeptide portion of the GP-2 subunit of laminin. Antibodies produced by the hybridomas have been shown to be IgG 2b (lambda) and IgG 2a (kappa), respectively. In competition ELISA assays the monoclonal antibodies exhibited different binding affinities for laminin. Furthermore, the two antibodies were partially additive in their reactivity to laminin. Preliminary results also indicate that the antibodies recognized different antigenic determinants in laminin as determined by their reactivity to basement membranes in human and mouse tissues. The monoclonal antibody designated LAM-I stained a broad spectrum of human and mouse tissues; the other monoclonal antibody LAM-II reacted with mouse, but not human tissues. The results indicate that these monoclonal antibodies could be utilized to explore the organization of laminin in basement membranes of different tissues and species.
