Data plotting of warfarin binding to human serum albumin.
The binding of warfarin to human serum albumin was studied by equilibrium dialysis at pH 7.4 in a 67 mM sodium phosphate buffer at 37 degrees C. The equilibrium data were analysed using a computer program for curve fitting. The analysis was made fitting the data to equations for one, two and three classes of binding sites with one, two and three sites at the primary binding site (n(1)=1, 2 or 3). The data fitting was acceptable for two and three classes of binding sites but the best fit was obtained with the equation for two classes of binding sites, allowing us to define the binding by a model with two independent classes of binding sites on the serum albumin molecule.
