Sigmoidal binding isotherm

WebThus, this binding isotherm was subjected to the Hill analysis (Figure 5c) to afford the Hill coefficient and the apparent binding constant (n = 10.2 and K a = 27 M –1). The cooperative binding (n > 1), i.e., sigmoidal binding isotherm, is a quite general behavior observed in a system where a positive homotropic allosterism is operative.
