Anita, If one of the partners is indeed more or less unfolded before interaction, then you should see a negative DeltaS upon complex formation. Practically, I would try first putting the unfolded protein in the cell and the folded one in the syringe in view of possible solubility problems with an "incorrectly" folded protein. Alanine scanning ? Yes on the paper, but may be less feasible in practice due to the amount of material to prepare.
