【Abstract】 The characteristics of the binding reaction of papaverine with BSA was studied by fluorescence spectroscopy. It was found that papaverine hydrochloride exhibits a strong quenching effect on the fluorescence of BSA through a non radiative energy transfer. The data of fluorescence quenching were analyzed according to Stern-Volmer equation and double-reciprocal equation, and the binding constant of the reaction, the position of binding and the basic thermodynamic parameters of the binding process were obtained.更多还原
