Concentration from Continuous Culture of Erythrocytes Infected with Trophozoites and Schizonts of Plasmodium Falciparum

Abstract

Gelatin, from readily available sources, at specified concentrations in RPMI 1640 medium enhances sedimentation rates of suspensions of Plasmodium falciparum-infected erythrocytes from continuous cultures, resulting in an enrichment of the trophozoite- and schizont-infected cells to parasitemias of 75% or more with no deleterious effects to the parasites.
