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.

Deriving mechanisms of immune-mediated disease from GWAS data remains a formidable challenge, with attempts to identify causal variants being frequently hampered by strong linkage disequilibrium. To determine whether causal variants could be identified from their functional effects, we adapted a

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

R-loops are dynamic, co-transcriptional nucleic acid structures that facilitate physiological processes but can also cause DNA damage in certain contexts. Perturbations of transcription or R-loop resolution are expected to change their genomic distribution. Next-generation sequencing approaches to map RNA-DNA hybrids

We describe a chemical method to detect RNA synthesis in cells, based on the biosynthetic incorporation of the uridine analog 5-ethynyluridine (EU) into newly transcribed RNA, on average once every 35 uridine residues in total RNA. EU-labeled cellular RNA is
