FRET-labeled telomerase RNA

Protocol 4 Splinted RNA ligation method for producing FRET-labeled telomerase RNA... [Pg.44]

We have developed the splinted RNA ligation procedure outlined in this chapter to generate site-specifically dye-labeled telomerase RNA constructs. These modified telomerase RNA constructs may be used to characterize dynamic RNA structural properties using Forster resonance energy transfer (FRET) (Stone et al., 2007). Our laboratory specializes in single molecule FRET measurements, which facilitates the direct observation of transient RNA structural states. The details of single molecule FRET... [Pg.46]
