中文摘要：
应用荧光光谱、紫外-可见分光光度法研究了盐酸鸟嘌呤（GH）与牛血清白蛋白（BSA）的相互作用。结果表明：GH能猝灭BSA的荧光强度，其猝灭机理为静态猝灭。采用位点结合模型公式和热力学公式计算了结合常数、结合位点数及结合类型。用同步荧光技术研究GH对BSA构象的影响。
英文摘要：
Mechanism of the interaction between guanine hydrochloride （GH） and bovine serum albumin （BSA） was studied by fluorospectrometry and UV-VIS spectrophotometry. Quenching of fluorescence of BSA was observed due to its reaction with GH, and the interaction was found to be a static quenching process. The binding constants, number of binding sites and types of binding force were found by applying the equation of site-binding model and thermodynamic equations. Synchronous fluorescence spectrometry was used in the study of the effect of GH on the configuration of BSA.
