Eryptosis hallmarks include PS exposure, cell size, intracellular calcium levels and hemolysis data (see Figure 4 and Supplementary Figures 1– 5 for detailed data on each compound). Ionomycin was used as a positive control. Significant changes (↑ = increase or ↓ = decrease) are indicated with the concentration at which the effect is observed. *: infected erythrocytes incubated with 5 μM benzethonium present an increase in hemolysis levels, which has not been observed at 10 μM.
