Fig. 2. pLL20/DNA complexes display increased aggregation in salt compared to pLL211/DNA. / pLL/DNAcp complexes were analyzed for light scattering on a Zetasizer photon correlation spectroscope in the presence or absence of 150 mM NaCl. pLL20/DNAcp (●, +NaCl; ♦, −NaCl); pLL211/DNAcp (▴, +NaCl; ▪, −NaCl); note that ♦ and ▪ are superimposed and therefore indistinguishable. Results show the mean ± SD of 3 independent experiments. Similar results were obtained using pLL/DNActcomplexes (data not shown).
