Efficient synchronization of Plasmodium knowlesi in vitro cultures using guanidine hydrochloride
Abstract Background Long-term in vitro culture of blood stage Plasmodium parasites invariably leads to asynchronous parasite development. The most often used technique to synchronize Plasmodium falciparum culture is sorbitol treatment, which differentially induces osmotic lysis of trophozoite- and s...
