Fig. 2From: Uptake of a fluorescently tagged chloroquine analogue is reduced in CQ-resistant compared to CQ-sensitive Plasmodium falciparum parasitesLive cell imaging of CQGREEN treated parasites. Synchronized trophozoite stage 3D7 parasites containing Ringer‘s or Equilibration Buffer solution for pH 7.2 and 5.2 were prepared for confocal microscopy. Different CQGREEN concentrations were added and uptake was monitored for 30 min, while emission range was set to 500–600 nm. Fluorescence increased with higher CQGREEN concentrations but no accumulation of CQGREEN could be detected in the parasite’s DV. Scale bar, 5 µmBack to article page
