Fig. 2From: pH-sensitive packaging of cationic particles by an anionic block copolymer shellInfluence of the amount of layer polymer on the stability of pDNA complexation by the PBMD polymer. pDNA binding after addition of increasing amount of layer polymer was evaluated by A gel electrophoresis (DNA: pDNA, 0: naked PBMD(pDNA) particle) and B ethidium bromide binding assay (EBA) at different pH values (HBG buffer pH 7.4, acetate buffer pH 6 and 5) at N/P 10 (n = 3). The obtained data were fitted using a b-spline functionBack to article page
