Regulation. Complete Freund’s adjuvant effectively stimulates cell-mediated immunity and leads to the enhancement of T helper cells, which leads to the production of certain immunoglobulins and effector T cells.its Regulators ban use in humansbecause of its toxicity.

How do adjuvants promote immunogenicity?

Adjuvants are agents that enhance the immunogenicity of an antigen. Adjuvants are used in the production of polyclonal and monoclonal antibodies. Adjuvants allow for prolonged and slow release of the antigen in vivo. Adjuvants also protect antigens through non-specific stimulation of immune responses.
