Preparative purification of Plasmodium falciparum circumsporozoite protein synthetic polypeptides by displacement chromatography.

Displacement chromatography was used for the preparative purification of a synthetic polypeptide that is a promising malaria vaccine. It was prepared by solid-phase synthesis and contains two important epitopes of circumsporozoite (CS) protein of Plasmodium falciparum sporozoite. With apparatus typically employed in analytical high-performance liquid chromatography (HPLC) and on a 250 x 4.
