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.

Ovarian tissue contains large pools of immature oocytes enclosed in primordial follicles, making it an attractive target for fertility preservation in female cancer patients, livestock and wild species. Compared to cryopreservation, desiccation and long-term storage of samples at supra-zero temperatures

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

GPN-loop GTPases 1 and 3 are required for RNA polymerase II (RNAPII) nuclear import. Gpn1 and Gpn3 display some sequence similarity, physically associate, and their protein expression levels are mutually dependent in human cells. We performed here Fluorescence Resonance Energy

Induction of biphasic interphase-mitotic cells and PCC is connected with an increased level of metabolism in root meristem cells of Allium cepa. Previous experiments using primary roots of Allium cepa exposed to low concentrations of hydroxyurea have shown that long-term
