Nanopore Direct RNA Sequencing of Monosome- and Polysome-Bound RNA

Abstract

Polysome fractionation makes use of density gradients and ultracentrifugation to separate transcripts based on their specific number of bound ribosomes, and can be combined with downstream analysis such as cDNA-seq (commonly known as RNA-seq), microarray analysis, RT-qPCR, or Northern blotting. Here, we describe the application of Nanopore direct RNA sequencing to quantify monosome- and polysome-bound full-length transcripts after polysome fractionation, RNA cleanup, and size selection, using the yeast glucose stress response as an example use case.
