Figure 2.

Experimental data of Phy (left) and dgPhy (right) plotted together with the calculated form factor (black solid line). The lower-concentration series (light gray) are ∼86 mg/ml and ∼52 mg/ml for Phy and dgPhy, respectively, and the higher-concentration series (dark gray) are ∼153 mg/ml and ∼80 mg/ml for Phy and dgPhy, respectively. The dotted, dashed, and dash-dotted lines represent concentrations of 0 M, 0.3 M, and 1.0 M NaCl, respectively.
