Heat induced denaturation of bovine serum albumin in dimethylsulfoxide containing solutions in the presence of potassium iodide Chemistry

Abstract

Heat induced denaturation of bovine serum albumin (BSA) in dimethylsulfoxide (DMSO) containing solutions in the presence of potassium iodide has been studied using UV/vis spectroscopy method. It has been shown that the thermal stability of protein depends on competitive interactions taking place in the solution. At low DMSO concentrations (5 vol. %) BSA is more stable than at higher concentrations (10–25 vol. %).
