Y. Hemar et Ds. Horne, ELECTROSTATIC INTERACTIONS IN ADSORBED PROTEIN LAYERS PROBED BY A SEDIMENTATION TECHNIQUE, Journal of colloid and interface science (Print), 206(1), 1998, pp. 138-145
A simple centrifugation technique has been used to determine the thick
nesses of layers of alpha(S1)-casein and beta-casein adsorbed onto mon
odisperse polystyrene latex particles. The influence of electrostatic
interactions within the layers on their thickness and stabilizing abil
ity is investigated by varying the ionic strength of the suspension or
by including calcium ions, known to bind specifically to the caseins.
