RNA-Seq Workflow and Data Analysis

Description

RNA sequencing, or RNA-Seq, is a high-throughput method for studying the transcriptome of a cell. The transcriptome is the full set of RNA molecules in a sample. Transcriptomics helps scientists understand how genomes work, how organisms develop, and how some diseases occur.

Transcript

RNA 测序 (RNA-seq) 是一种高通量测序技术,可识别和定量样品中的 RNA 序列。

它可用于分析总 RNA 或特异性 RNA 群,如 mRNA、tRNA、rRNA 和 miRNA。该技术在转录组分析、差异基因表达分析和 RNA 编辑方面有多种应用。

在分析特定群体的情况下,需要从其他 RNA 中分离感兴趣的 RNA 类型。可以使用与 mRNA 转录本上存在的 poly A 尾互补的 oligo dT 探针分离 mRNA。MicroRNA 通常长约 15 到 30 个核苷酸,通过基于大小的提取方法进行分离。

或者,可以使用与污染物互补并与磁珠共价连接的寡核苷酸去除污染 RNA,例如核糖体 RNA。使用磁铁将杂交的核糖体 RNA 与样品...
