Abstract
Novel method, cells and compositions are provided involving transforming B-lymphocytes to provide immortalization for continuous production of monoclonal antibodies to a predetermined ligand. T-cell free B-lymphocytes are combined with an Epstein-Barr virus transformed cell sensitive to a cytotoxic agent which does not significantly affect the B-lymphocytes under conditions where the sensitive EBV transformed cell acting as the transfer agent is killed and efficiently transforms the B-lymphocyte recipient cells with EBV. The EBV transformed B-lymphocyte cells are amplified and cloned, the desired clones isolated in accordance with conventional techniques and then used for production of monoclonal antibodies.
