Figure 3

Comparison of the emitted fluorescence signals and parasitemia detected by fluorescence- and microscopy-based methods, respectively, using different concentrations of SYBR Green I stain. (a) Microscopy-based method; (b) fluorescence-based method using 1x SG I stain; (c) fluorescence-based method using 2x SG I stain; (d) fluorescence-based method using 4x SG I stain; (e) fluorescence-based method using 8x SG I stain. Each value represents the mean ± standard deviation of 5 mice per experimental group after subtracting the background fluorescence for non-parasitized RBCs from uninfected mice. Gain values are not set to 100.
