We recently developed a novel transcriptome analysis method, termed 5'-bromo-uridine (BrU) immunoprecipitation chase-deep sequencing analysis (BRIC-seq). BRIC-seq enables the determination of genome-wide RNA stability by chasing chronological decreases of BrU-labeled RNAs under physiologically undisturbed conditions. The RNA half-life of each transcript is calculated from the decreasing number of BrU-labeled RNA sequence tags measured by deep sequencing of BrU-labeled RNAs. Here, we describe a detailed protocol and provide tips for BRIC-seq, followed by computational analysis.
我们最近开发了一种新型转录组分析方法,称为5'-溴尿苷(BrU)免疫沉淀追踪深度测序分析(BRIC-seq)。BRIC-seq能够在生理条件未受干扰的情况下,通过追踪BrU标记RNA随时间的减少来测定全基因组范围内的RNA稳定性。每个转录本的RNA半衰期是根据对BrU标记RNA进行深度测序所测得的BrU标记RNA序列标签数量的减少来计算的。在此,我们描述了BRIC-seq的详细方案并提供了相关提示,随后是计算分析。
