Isobolograms showing the interaction between dihydroartemisinin and emetine. The fixed ratio method was used to analyse the interaction between dihydroartemisinin and emetine dihydrochloride hydrate against trophozoite stage parasites. Treatments were set up in duplicate for 48 hours and analysed using the SYBR Green flow cytometer method. The FIC50(a) and FIC90(b) concentrations were determined and used to plot the isobologram.
