This communication describes a general approach for site-specific fluorescence labelling of RNA using a cytidine triphosphate (CTP) analogue derivatized with a trans-cyclooctene group. The analogue was efficiently incorporated into a model RNA strand using in vitro transcription. Bio-orthogonal reaction with fluorescein-labelled tetrazine was utilized to fluorescently tag the synthetic RNA strand.
本通讯描述了一种使用经反式环辛烯基团衍生化的三磷酸胞苷（CTP）类似物对RNA进行位点特异性荧光标记的通用方法。该类似物通过体外转录被有效地掺入到模型RNA链中。利用与荧光素标记的四嗪进行的生物正交反应对合成的RNA链进行荧光标记。
