Cell viability assay after sDNA transfection. (A) Miapaca-2 and (B) AsPC-1 cells were transfected with two doses of sDNA. Cells were fixed 48 and 96 h after transfection and analyzed with the crystal violet assay as described in the methods. The absorbance was measured at 570 nm in quadruplicate. All data from control cells were combined and averaged. The values were analyzed pair wise with TC using a student t-test, with p values <0.05 considered a significant change (*p < 0.05, **p < 0.01).
