basic biological research but there are currently only a limited number of probes available for the detection of non-enzymatic proteins. Here, we report turn-on fluorescent probes mediated by conjugate addition and cyclization (TCC probes). These probes react with multiple amino acids and exhibit a 36-fold greater emission intensity after reaction. We analyzed the reactions between TCC probes and nuclear
荧光分子为基础生物学研究做出了贡献,但是目前只有少数几种探针可用于检测非酶蛋白。在这里,我们报告由缀合物添加和环化介导的开启荧光探针(TCC探针)。这些探针与多种氨基酸反应,反应后发射强度提高36倍。我们通过电喷雾电离质谱,X射线晶体学,荧光光谱和荧光显微镜分析了TCC探针和核受体之间的反应。体外分析表明,由蛋白质配体和TCC组成的探针可以标记维生素D受体和过氧化物酶体增殖物激活的受体γ。此外,
