Electrokinetic charge (${\sigma }_{ek}$), obtained by Ohshima’s equation (Equation (5)), for the complexes consisting of proteins + anionic or cationic latex and effective charge (${\sigma }_{eff}$) due to adsorbed protein taking into account ion condensation (Bocquet et al. model) for (a) $\beta$-casein; (b) $\beta$-lactoglobulin and (c) BSA. The star indicates the theoretical pI of the proteins from Propka calculations. The solid and dashed lines are used for guiding the eye.
