 Use of freund's complete adjuvant


Complete Freund's adjuvant (CFA) is an immunoadjuvant emulsified with antigen by its discoverer Jules T. Freund to enhance an animal's immune response to an antigen. Complete Freund's adjuvant (CFA) is also an inducer of the Th1 immune response and a ligand of TLRs. Complete Freund's adjuvant (CFA) contains heat-killed inactive tuberculosis bacilli and consists of a paraffin oil-in-water emulsion. Complete Freund's adjuvant (CFA) stimulates a strong and durable immune response and can be used to induce persistent inflammatory pain models in mice, experimental autoimmune myocarditis (EAM) models, and more. Incomplete Freund's adjuvant (IFA) (HY-153808A) is another type of Freund's Adjuvant that stimulates a weaker immune response[1][2].
