Kohler and Milstein developed biotechnology for production of A) Modern vaccines B) Immobilined enzymes C) Monoclonal antibodies D) Myelomas
Option C) Monoclonal antibodies are monospecific antibodies that are made by identical immune cells that are all clones of a unique parent cell. In 1975, Georges Kohler and Cesar Milstein succeeded in making fusions of myeloma cell lines with B cells to produce hybridomas that made antibodies to known antigens. Monoclonal antibodies were first produced by applying the techniques of somatic cell genetics to antibody-producing cells. The cells that produce antibodies (B cells) are short-lived in culture. Thus, attempts to maintain B cells in culture and harvest antibody specificities failed for many years until Cesar Milstein and George Koehler succeeded in immortalising B cells via somatic cell hybridisation.
