Figure 2From: Optimization of DNA delivery by three classes of hybrid nanoparticle/DNA complexesQuality control for pLuc DNA adsorbed to either surface NPs (out and both) or encapsulated NPs (in and both). The NP/DNA complexes were treated with or without DNase I and delivered to 293 cells for 48 hours. Lipofectamine 2000 with pLuc DNA was a positive control (Lip) and untreated 293 cells was the negative control (NC). The assay measures luciferase activity.Back to article page
