5-Vinyl-uridine (VU) is a uridine derivative with a terminal alkene group that can be used for monitoring and investigating RNA transcription in cells instead of 5-ethynyl-uridine (EU).

VU is readily taken up by living cells and incorporated by RNA polymerases into de novo RNA instead of endogenous uridine, but not into DNA [1]. VU-labeled nascent cellular RNA can be detected quickly and with high sensitivity via inverse electron-demand Diels-Alder cycloaddition reaction (IEDDA) between the vinyl group and fluorescently or biotin-labeled tetrazines.

Labeled RNA can be detected with different cell transcriptional levels estimation methods, e.g., fluorescent microscopy or flow cytometry.

FAM tetrazine, 5-isomer

FAM tetrazine (methyltetrazine) for the conjugation with trans-cyclooctenes and cyclopropenes. Pure 5-isomer of fluorescein.

EdU (5-Ethynyl-2'-deoxyuridine)

EdU is a nucleoside that is incorporated into replicated DNA by cellular enzymes. After it, DNA contained in the cells can be developed by click chemistry reaction with fluorescent dye azides to reveal cell proliferation.
