Figure 1From: Evaluation of bioluminescence-based assays of anti-malarial drug activityCorrelation of luciferase assay activity with haematocrit and parasitaemia. Luciferase activity (RLU) from trophozoite stage Dd2luc was plotted over a range of parasitaemias from cultures at three haematocrit (1, 2 and 4%, see legend). The mean RLU ± stdev (n = 5) are plotted with a linear regression line (R2 > 0.97 in all cases).Back to article page
