利用紫外光谱,以曙红Y(Eos in Y)为探针,考察了稀土杂多配合物K15[C e(BW11O39)2].17H2O与牛血清白蛋白(BSA)间的作用,K15[C e(BW11O39)2].17H2O与Eos in Y在BSA上有竞争结合,表面活性剂对两者间的竞争结合有增敏作用;并利用荧光光谱直接考察了K15[C e(BW11O39)2].17H2O与BSA的相互作用及其对BSA构象的影响。
The effect of rare earth heteropoly complex K15 [C e (BW11O39) 2] .17H2O and bovine serum albumin (BSA) was investigated by ultraviolet spectroscopy and Eos in Y. K15 [C (BW11O39) 2] .17H2O competed with Eos in Y on BSA, and the surfactant had a sensitizing effect on the competitive binding between the two. The fluorescence spectra of K15 [C e (BW11O39) 2] .17H2O Interaction with BSA and Its Effect on the Conformation of BSA.
