^aDifference of preferential interaction coefficients between associated and free proteins.

^bRegional preferential interaction coefficients at the protein-protein interface region inte(D) and the complementary protein surface region non-inte(D). The distance D is 7 Å for the D1.3-lysozyme complex and 9 Å for the D44.1-lysozyme complex.

^cCalculated from experimental K_A-values at 6 molal glycerol (Figure 1).
