(a) Particle size analysis of cKH-FGF2/pDNA and dKH-FGF2/pDNA complexes at various N/P ratios in the presence of 10 mM phosphate buffer and 5 mM NaCl. (b) Stability of cKH-FGF2/pDNA and dKH-FGF2/pDNA complexes in the presence of 10 mM phosphate buffer and 150 mM NaCl are demonstrated. Complexes were formed at N/P ratio of 1. For particles formed with cKH-FGF2, the size slightly increased from 115 nm ± 15 to 156 ± 13, but remained stable over 55 min. For particles formed with dKH-FGF2, the size increased steadily from 205±16 nm to 668±24 nm.
