WebA convenient metric for characterizing binding curve line shapes is their midpoint slope, which can be computed from Eq. 3 as follows. The logarithmic derivative of the binding relation is given by ∂ v ∂ ( logx) = xln(10) ∂ v ∂ x, (7) where the substitution log x = (ln x )/ (ln10) was used. The regular derivative of the binding relation is given by Binding curves showing the characteristically sigmoidal curves generated by using the Hill–Langmuir equation to model cooperative binding.
