s can normally be described by their affinities for each other. The interactions of clustered proteins for multivalent ligands are described by avidities (

avidity In biochemistry, avidity refers to the accumulated strength of ''multiple'' affinities of individual non-covalent binding interactions, such as between a protein receptor and its ligand, and is commonly referred to as functional affinity. Avidity d ...
