Figure 5: Viability of HeLa, A549, Huvec, and NIH-3T3 cells after incubation with different concentrations of Cyt c-HA 8kDa and Cyt c-HA 1MDa. Cells were incubated for 24 h with Cyt c-HA 8kDa (upper panel) and Cyt c-HA 1MDa (lower panel). Asterisks (*) indicate statistically significant difference from the control (HA) in corresponding cell line, p<0.05, ** p<0.001, and *** p<0.0001.
