KLK and KPK do not affect cell-viability. CHO-K1, HeLa and T24 cells were treated with KLK or KPK at the indicated concentrations for 15 min. The ability of all three cell lines to convert the non-fluorescent Resazurin into its fluorescent derivate Resorufin was not reduced for the analyzed cells. The viability of the cells was calculated from 5 individual measurements, and normalized to untreated cells. Error bars are based on the standard error of the mean.
