(a) CD spectra of PEG-PF4ZIP at different concentrations in PBS at 25 °C. (b) Concentration dependence of the MRE for PEG-PF4ZIP at 222 nm. The solid line is the best fit according to Eq. (A4) for Kd = 0.93 ± 0.01 μM. θ0 was fixed at 2500 deg cm2 dmol-1. The errors are derived from the average of duplicate measurements.
