Optimization of pVEGF transfection using PAM-ABP. (a) The pβ-SP-ODD-VEGF was transfected to H9C2 cells using PAM-ABP at three different weight ratios and branched PEI (25 kDa), a positive control, at a weight ratio of 1. VEGF secretion was quantitatively determined using an ELISA kit at 48 hours post-transfection. (b) Cell viability was measured by MTT assay under the same conditions used in (a). The data are presented as the mean ± the SD of three independent measurements. C and ND indicate control and naked plasmid DNA, respectively.
