A molecular probe for the luminescent detection of nucleotides (e.g., adenosine nucleotides) is presented. In certain embodiments, the probe can readily distinguish between the three adenosine nucleotides in buffered aqueous conditions at neutral pH, a need for the direct monitoring of enzymatic reactions converting ATP to ADP or AMP. The probe is most efficient under millimolar concentrations of ATP, which are relevant to intracellular conditions. In preferred embodiments, the long luminescence lifetime of the probe readily enables time-gating experiments.
本文介绍了一种用于发光检测核苷酸(例如
腺苷酸)的分子探针。在某些实施例中,该探针可以在缓冲的
水溶液中,在中性pH条件下轻松区分三种
腺苷酸,这是直接监测将
ATP转化为
ADP或
AMP的酶反应的需要。该探针在毫摩尔浓度的
ATP下最有效,这与细胞内条件相关。在首选实施例中,探针的长发光寿命可轻松实现时间分段实验。
