(a) Cell viability assays on HT-29 cells after a 72-h continuous incubation at 37 °C for BSA-PEI (1:2, w/w) and BSA-PEI-PEG5k(OAOA-L-CHO)4 (1:2:2, w/w) complexes. (b) IC50 values calculated from the cell viability results in a. The errors in a and b are for standard deviation (n = 3, *P < 0.05, **P < 0.01). (c,d) Hemolytic assays for (c) BSA-PEI (1:2, w/w) and (d) BSA-PEI-PEG5k(OAOA-L-CHO)4 (1:2:2, w/w) complexes. The error is for standard deviation (n = 3).
