Monoclonal Antibodies and Growth Environment
Monoclonal antibodies come from clones of B cells that produce a single antibody of known specificity. B cells will nor normally divide in the absence of antibody. The special trick that allowed monoclonal antibody-producing cells to be grown in culture was: (a) Mice were immunized with antigen and T cells removed and grown ...continues
