title: Human serologic response to subcellular antigens of Trichomonas vaginalis.
abstract: Trichomonas vaginalis organisms were processed by differential centrifugation to yield defined subcellular fractions. The various fractions were processed by methods to enhance solubility of membranes and other components. The soluble materials were analyzed for immunogenicity by a quantitative kinetic enzyme-linked immunosorbent assay (k-ELISA) and the enzyme-linked immunoelectrotransfer blot (EITB) technique using human patient serum. The principal antibodies in the human serum were directed toward cytosol components, not against membrane components, although all fractions contained multiple antigenic moieties.
