ABSTRACT:
A method for the solubilization and recovery of insoluble parasite protective antigenic factors associated with parasite material comprising solubilizing the antigenic factors with a non-ionic detergent and separating the solubilized material from undispersed residual material. The purified protective antigenic factors are useful as vaccines, particularly against malaria, and as diagnostic agents.
