Force spectra taken on raised terraces and lower features.
Rupture force distribution of self assembled gp160 unfolding on terraced and lower regions.
Rupture forces were measured as 79.6 ± 3.9 pN and 81.3 ± 3.8 pN for the terraces and lower regions, respectively.
Sawtooth pattern on the retraction force curve indicating the unfolding of fibronectin. The average rupture force distribution of the protein on mica surface was 85.1 ± 2.7 pN.
