Effects of polyelectrolyte chain stiffness, charge mobility, and charge sequences on binding to proteins and micelles.
The binding affinities of polyanions for bovine serum albumin in NaCl solutions from I = 0.01-0.6 M, were evaluated on the basis of the pH at the point of incipient binding, converting each such pH(c) value into a critical protein charge Zc. Analogous values of critical charge for mixed micelles were obtained as the cationic surfactant mole fraction Yc. The data were well fitted as Yc or Zc = K...
