Updated guide to RNA quantification by RNA sequencing and reverse transcription-qPCR.

RNA sequencing (RNA-seq) and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) are widely used for RNA quantification. RNA species with distinct structural and biogenetic features require specific computational and experimental approaches. Here, we provide an updated MiniResource that extends our previous guides to RNA-seq analysis and RT-qPCR-based RNA quantification. We introduce available tools and key considerations for analyzing circular RNAs, double-stranded RNAs, ribosomal RNAs, and transfer RNAs. This guide will help researchers choose appropriate methods for RNA species-specific quantification.
