| Abstract: | A method of analyzing the result of continuous ultrafiltration experiments to obtain protein-ligand binding parameters is presented. This method employs a nonlinear least-squares regression algorithm coupled with a model of protein-ligand binding which alloww the computation of free ligand concentrations, and a second-order Runge-Kutta method to integrate free concentrations with respect to collected ultrafiltrate. The approach is general and effectively removes the constraints on maximum fraction size imposed by other methods. |
