Figure 5. Thermodynamic cycle used to calculate the binding free energies between MHC class II molecule and the epitope peptide.

Figure 5

The diagram shows the thermodynamic cycle for the binding of a MHC class II molecule and a epitope peptide, in both the solvated phase and in vacuo. The free energy of binding in solvent can be calculated by the following equation: Inline graphic.
