Blood clearance of plasmid DNA after delivery in arginine/DNA complexes. Plasmid DNA (100 μg) complexed with arginine peptide at an N/P ratio of 3:1 was intraperitoneally administered to mice. DNA was extracted from blood at the indicated time points and used for nested PCR products. The nested PCR products were separated on a 1.2% agarose gel.
