Dose-responsive cell viability of (a) MDA-MB-231 and (b) HeLa cells exposed to the eGFP-siRNA-loaded, A-cross-linked, acid-degradable DODAP-(left blue bar); DOTAP-PCLs (middle green bar); and eGFP-siRNA-loaded Lipofectamine 2000 (LF, right red bar) at 37 °C for 24 h. After rinsing off the excess siRNA-containing formulations, the cells were further incubated at 37 °C for 48 h before cell viability was measured using MTS assay. Error bars indicate the standard deviation of the mean with n = 3.
