5'-Bromouridine IP Chase (BRIC)-Seq to Determine RNA Half-Lives.

Analysis of RNA stability at genome-wide level is an advanced method in RNA biology that examines the half-life of each transcript. In particular, a pulse-labeling method using uridine analogs enables the determination of half-life of each transcript under physiologically undisturbed conditions. The technique involves pulse labeling of endogenous RNAs in mammalian cells with 5'-bromouridine (BrU), followed by measuring the chronological decrease of BrU-labeled RNAs using deep sequencing (BRIC-seq). Here, we describe a detailed protocol and technical tips for BRIC-seq.
