Fig. 3From: Redox-Sensitive Gelatin/Silica-Aptamer Nanogels for Targeted siRNA DeliveryAGE analysis of siRNA reversible binding to Apt-GS nanogels. Lanes 1–5: free siRNA with amount of 50, 40, 30, 20, and 10 pmol. Lanes 6 and 7:GS/siRNA and Apt-GS/siRNA with 10 mM GSH at 2 h. Lane 8: the mixture of free siRNA and Apt-GS NGs. Lanes 10 and 11: GS/siRNA and Apt-GS/siRNA complexes without 10 mM GSH as controlsBack to article page
