Application

This alkyne-bearing metabolic labeling reagent can be used to measure RNA synthesis in proliferating cells. Once fed to cells, this nucleoside is incorporated during active RNA synthesis and can then be detected using a copper-catalyzed click reaction with fluorescent dyes. The cells can then be analysed by fluorescence imaging, flow cytometry or high content imaging analysis.

Repair of DNA double-strand breaks (DSBs) is essential for genome integrity, and is accompanied by transcriptional repression at the DSB regions. However, the mechanisms how DNA repair induces transcriptional inhibition remain elusive. Here, it is identified that BRD7 participates in

We combine the labeling of newly transcribed RNAs with 5-ethynyluridine with the characterization of bound proteins. This approach, named capture of the newly transcribed RNA interactome using click chemistry (RICK), systematically captures proteins bound to a wide range of RNAs
