In the native bovine casein micelle the calcium sensitive caseins (αS1-, αS2- and β-casein) sequester amorphous calcium phosphate in nanometer-sized clusters, whereas the calcium-insensitive κ-casein limits the growth of the micelle. In this paper, we further investigate the self-association of κ- a...
