We performed single molecule dynamic force spectroscopy experiments to study the dimerization of two amyloid-β (1-42) peptides and compared three different theoretical models used to fit experimental data: Bell-Evans, Dudko-Hummer-Szabo, and Friddle-De Yoreo.  All three models corrected for the linker effect give comparable results for xβ and show more discrepancy for k0 and ΔG values, ΔG parameter correlates well between Dudko-Hummer-Szabo and Friddle-De Yoreo models but differs for the Bell-Evans model.
