Description: | 5-Ethynyluridine (5-EU) is a potent cell-permeable nucleoside can be used to label newly synthesized RNA. 5-Ethynyluridine can be used for isolation and sequencing of nascent RNA from neuronal populations in vivo. 5-Ethynyluridine can be used to identify changes in transcription in vivo in nervous system disease models. |
In Vivo: | 5-Ethynyluridine (75 mM in PBS for 1 µl; intracerebellar injection ) shows a labeling of central nervous system cells in mouse[1]. 5-Ethynyluridine (330-750 µMol/g; i.p.) results in in labelling of nascent RNA in cells of multiple organs and tissues, but not in the central nervous system in mouse[1]. |
