Fig. 3From: In Vivo Bio-distribution and Efficient Tumor Targeting of Gelatin/Silica Nanoparticles for Gene DeliveryGel electrophoresis assay of NP/DNA complexes. Lane 1: marker; Lane 2: naked DNA (ND); Lanes 3–4: GS/DNA complexes; Lanes 5–6: GS-PEG-Apt/DNA complexes; Lanes 7–8: GS-PEG/HA2-Apt/DNA complexes. Complexes with GS/DNA weight ratio of 200 (lanes 3, 5, and 7) and 100 (lanes 4, 6, and 8) were investigated in deionized waterBack to article page
