This unit discusses several methods for generating large amounts of uniformly labeled, end-labeled, and site-specifically labeled RNAs in vitro. The methods involve a number of experimental procedures, including RNA transcription, 5′ dephosphorylation and rephosphorylation, 3′ terminal nucleotide addition (via ligation), site-specific RNase H cleavage directed by 2′-O-methyl RNA-DNA chimeras, and 2-piece splint ligation. The applications of these RNA radiolabeling approaches are also discussed. Curr. Protoc. Mol. Biol. 102:4.15.1–4.15.14. © 2013 by John Wiley & Sons, Inc.
