Fig. 1From: A high-throughput colorimetric assay for detection of Schistosoma mansoni viability based on the tetrazolium salt XTTAbsorbance levels of formazan product for different parasites concentration over time. Mechanically transformed schistosomula were distributed in 96-well plates at the concentrations of 100, 200, 300 and 400 parasites per well. Schistosomula were cultured for 48 h before addition of XTT labeling mixture. Parasites were incubated with XTT labelling mixture for 4, 6 and 24 h before absorbance measurements. Linear regression r 2 values are indicated on the graphBack to article page
