Studies on the immunology of human malaria. II. Characterization of antibodies to Plasmodium falciparum infections.

Gel precipitin and fluorescent antibodies to human malaria have been investigated using techniques of comparative immunoelectrophoresis, gel-filtration and DEAE-cellulose chromatography. Antibody activity was generally associated with the IgG class but some gel precipitin antibodies of IgM type were identified. Findings in regard to antibody activity in the IgA class were inconclusive.
