a, Force–extension curve for a TNfnA-D protein. The smooth curve corresponds to the fit of an individual force–extension peak to the WLC equation F(x) = kT/p(x/l_c + 1/4(1 - x/l_c)² - 1/4). b, c, A family of WLC curves generated with the parameters found in a describes the force–extension curves of the TNfnALL protein (b; dotted lines) and of native dithiothreitol-treated tenascin (c; dotted lines).
