New hydrophobic intramolecular charge transfer probes, comprising an aminostyryl and a cyanopyranyl moieties, were developed for sensitive protein quantification in solution. The probes exhibited dramatic increase of fluorescence quantum yields with accompanying blue-shift of the emission when bound to protein–sodium dodecyl sulfate (SDS) complexes. Using this emission enhancement, the synthesized probes were successfully applied for determining protein concentrations in solution.
新开发的疏水性分子内电荷转移探针由氨基苯乙烯基和氰基吡喃基组成,可用于溶液中蛋白质的灵敏定量。当这些探针与蛋白质-十二烷基硫酸钠(SDS)复合物结合时,其荧光量子产率会显著增加,并伴随着发射蓝移。利用这种发射增强效应,合成的探针被成功地用于测定溶液中的蛋白质浓度。
