摘要
用荧光光谱法研究了在三羟甲基氨基甲烷 -盐酸缓冲溶液中 ,牛血清白蛋白 (BSA)增敏双嘧达莫荧光的荧光光谱特征 ,提出了在这种三羟甲基氨基甲烷 -盐酸 -牛血清白蛋白的水溶液介质新体系中测定双嘧达莫含量的新方法。方法灵敏度高 ,检出限低 ,在 1 .98× 1 0 -7~ 2 .3 8× 1 0 -6
The influence of BSA on the fluorescence property of dipyidamole was studied in Tris-HCl buffered solution.It was found that the fluorescence intensity of dipyridamole was greatly enhanced in Tris-HCl-BSA.A new fluorescence method for the determination of dipyridamole was proposed with high sensitivity and selectivity.
