Non-detergent sulphobetaines enhance the recovery of membrane and/or cytoskeleton-associated proteins and active proteases from erythrocytes infected by Plasmodium falciparum

Eur J Biochem. 1998 Mar 15;252(3):537-41. doi: 10.1046/j.1432-1327.1998.2520537.x.

Abstract

A better understanding of the causative agent's biology and the definition of new targets for the development of drugs and/or specific immune responses is necessary to face the spred of drug-resistant malaria in developing countries and the absence of an efficient vaccine against this most important infectious disease. Non-detergent sulphobetaines enhance the recovery and isoelectric focussing of active Plasmodium falciparum proteases, cytoskeleton-associated proteins and Maurer's cleft-associated proteins. This is a significant advantage for the purification of such proteins and might help pinpoint their role for red blood cell rupture and merozoite release.
