Fig. 4.

Dynamic force spectra. (A) Dynamic force spectra for the rupture of one (□), two (⋄), and three (▿) MUC1–Ab bonds. The loading rates for the multibond rupture events were normalized by the number of bonds. Solid lines represent the best fits of each spectrum to Eq. 1. (B–D) Histograms of normalized residuals from A for one (B), two (C), and three (D) bonds. The residuals were normalized by the corresponding value of the force scale f_β. Solid lines are Gaussian fits with the width of one, two, and three, respectively.
