Imaging Newly Transcribed RNA in Cells by Using a Clickable Azide-Modified UTP Analog.
Robust RNA labeling and imaging methods that enable the understanding of cellular RNA biogenesis and function are highly desired. In this context, we describe a practical chemical labeling method based on a bioorthogonal reaction, namely, azide-alkyne cycloaddition reaction, which facilitates the fluorescence imaging of newly transcribed RNA in both fixed and live cells. This strategy involves the transfection of an azide-modified UTP analog (AMUTP) into mammalian cells, which gets specifically incorporated into RNA transcripts by RNA polymerases present inside the cells. Subsequent posttranscriptional click reaction between azide-labeled RNA transcripts and a fluorescent alkyne substrate enables the imaging of newly synthesized RNA in cells by confocal microscopy. Typically, 50 μM to 1 mM of AMUTP and a transfection time of 15-60 min produce significant fluorescence signal from labeled RNA transcripts in cells.
