title: The use of polyclonal activators in the production of murine monoclonal and polyclonal antibodies.
abstract: We propose a new immunization method to stimulate a strong immune response against weak or diluted antigens. This technique is based on stimulation with polyclonal activators before exposure to the antigens. We also discuss the efficiency of various types of mitogen with particular regard to their capacity to produce monoclonal antibodies and serum antibodies. A specific immune response against soluble antigens is increased by pretreating mice with PPD. This preactivation permitted us to obtain monoclonal antibodies against weak antigens in a few days. No monoclonal antibodies were obtained by inoculating weak antigens or the activators by themselves.
