A series of six, cationic, zwitterionic and anionic Eu complexes has been examined for the analysis of hydrogencarbonate concentration in the intracellular and extracellular ranges; an anionic complex incorporating three glutarate residues and a sensitising acridone chromophore (λexc
= 410 nm) exhibits a 69% change in the intensity ratio of the 618/588 nm Eu emission bands between 5 and 15 mM HCO3– in a cell lysate medium.
为了分析细胞内和细胞外的
碳酸氢盐浓度,我们研究了一系列六种阳离子、齐聚离子和阴离子 Eu 复合物;其中一种阴离子复合物含有三个
戊二酸残基和一个敏化
吖啶酮发色团(λexc = 410 nm),在细胞裂解
培养基中,5 至 15 mM HCO3- 之间 618/588 nm Eu 发射带的强度比变化了 69%。
