    Recent evidence indicates that membrane-bound immunoglobulin on B lymphocytes is associated with a molecule which comprises the products of the mb-1 and B29 genes. This molecule is a highly specific marker for B-cells, presumably because of its central functional role

    Two monoclonal antibodies (LN-1, LN-2) reactive with B lymphocytes in B5 formalin-fixed, paraffin-embedded tissue sections have been produced by utilizing cell extracts from pokeweed mitogen-stimulated peripheral blood lymphocytes and diffuse histiocytic lymphoma SU-DHL-4 cells, respectively. Both monoclonal antibodies were initially

    Monoclonal antibodies (MoAbs) to B cell- and T cell-specific antigens uniformly have been restricted in their use to cell suspension or frozen section techniques because the antigens that they identify are either masked or lost in the fixation or paraffin-embedding
