A:T base pairs are thus favored because they are more readily distorted to allow the initial opening of the minor groove. There are also extensive interactions between the phosphate backbone and basic residues in the b sheet, adding to the overall binding energy of the interaction.

 Scatchard plots are based on repeated equilibrium dialyses with a constant concentration of antibody and varying concentration of ligand. 
If all antibodies have the same affinity, then a Scatchard plot yields a straight line with a slope of Ka. The x intercept is n, the valency of the antibody, which is 2 for IgG and other divalent Igs. For IgM, which is pentameric, n  10, and for dimeric IgA, n  4. In this graph, antibody #1 has a higher affinity than antibody #2.
