Concentration of DRS-B2 that inhibits 50% cell growth (GI50) extracted from S2 Fig.

Proliferation of each cell type was performed in plastic 24-well plates (1.91 cm2; cell density of 1x104 cells/well/0.5 mL). On the first and third day after plating, the cells were treated with DRS-B2 at different concentrations ranging from 0 to 10 μM. Twenty four hours after the last treatment cell counting was performed with crystal violet staining as described in Materials and Methods section. Results are represented in peptide concentration inhibiting 50% of the cell growth GI50 ± SD of at least three determinations.
