[Adjuvant effect of Quil-A on the porcine humoral immune response (author's transl)].

Quil-A, a purified extract of saponin, was analyzed for its adjuvant properties in the porcine humoral immune response against lysozyme. The adjuvant properties of Quil-A are comparable to the oil adjuvant properties in the pig. The optimal dose was found to be 1 mg per pig. Quil-A enhanced also slightly the homocytotropic antibodies.
