5-Ethynyl-uridine (5-EU)

• Catalog Number: orb65697
• Category: Small Molecules
• Description: Ethynyl-labeled uridine (5-EU) can be used as a replacement for BrU (5-Bromo-uridine) to measure de novo RNA synthesis in proliferating cells. 5-EU is cell permeable and incorporates into nascent RNA instead of its natural analog uridine. The resulting ethynyl-functionalized RNA can subsequently be detected via Cu(I)-catalyzed click chemistry that offers the choice to introduce a Biotin group (via Azides of Biotin) for subsequent purification tasks or a fluorescent group (via Azides of fluorescent dyes) for subsequent microscopic imaging. Long term storage at < -20°C. If stored as recommended, Biorbyt guarantees optimal performance of this product for 12 months after date of delivery.
