Abstract  

Thermodynamics of the interaction between erbium(III) chloride, Er3+, with human serum albumin (HSA), was investigated at pH 7.0 and in phosphate buffer by isothermal titration calorimetry. Our recently, solvation model was used to reproduce the enthalpies of HSA interaction by Er3+ over a broad range of metal ion concentration. The solvation parameters recovered from our new model, attributed to the structural change of HSA and its biological activity. The binding parameters for the interaction of Er3+ and HSA indicate that the concentrations of Er3+ have no significant effects on the structure of HSA.
