Treatment with BAT monoclonal antibody decreases tumor burden in a murine model of leukemia/lymphoma.

BAT is a monoclonal antibody produced against membranes of Daudi cells that induces anti-tumor activity in mice against a variety of solid murine and human tumors, mediated by its immune stimulatory properties on murine and human lymphocytes. The present study analyzes the effect of BAT on leukemia/lymphoma using the BCL1 model of leukemia/lymphoma in BALB/C mice. BAT antibody binds to BCL1 leukemia cells and recognizes a 48 kDa protein similar to the antigen on Daudi cells.
