Figure 3. Salt and urea stability of polyelectrolyte complexes.

Figure 3

(a) Turbidity as a function of NaCl concentration for various liquid coacervates (open symbols) and solid precipitates (solid symbols) prepared at 1 mM total residue concentration and pH=7.0. Error bars are the s.d. from triplicate measurements. (b) Optical micrographs showing the transition from solid precipitate to liquid coacervate for pLK+pLE complexes with increasing urea concentration. Scale bars, 25 μm.
