Figure 3From: Development of a colloidal gold-based lateral flow dipstick immunoassay for rapid qualitative and semi-quantitative analysis of artesunate and dihydroartemisininStandard inhibition curve of artemisinin in icELISA format. B0 and B are absorbance in the absence and presence of competitors, respectively. Concentration causing 50% inhibition by artemisinin was 96 ng mL-1. Each value represents the mean of three replicates.Back to article page
