Polymer protection of pDNA from serum nuclease degradation over time. Free pDNA or polymer/pDNA mixtures at increasing polymer concentrations were incubated in 90% fresh rabbit serum. Samples were taken at 0, 1, 2, 4 and 6 hr and evaluated for intact pDNA using gel electrophoresis (1% agarose). Percent intact pDNA was normalized to the amount of intact free (unprotected) pDNA at 0 hrs. using GelDoc software.
