A modified Plasmodium falciparum growth inhibition assay (GIA) to assess activity of plasma from malaria endemic areas

Exp Parasitol. 2007 Feb;115(2):211-4. doi: 10.1016/j.exppara.2006.08.003. Epub 2006 Sep 20.

Abstract

Plasma samples from patients undergoing treatment in malaria endemic countries often contain anti-malaria drugs, that may overstate effects of specific antibodies in growth inhibition assays (GIA). We describe a modified assay that uses drug resistant P. falciparum parasites (W2) that circumvents the requirement for dialyzing samples that may likely contain drugs such as chloroquine and sulfadoxine/pyrimethamine (SP).
