Esgotamento de RNA ribossômico para metagenomico Gut Mosquito RNA-seq

Overview

This article presents a protocol for depleting ribosomal RNA (rRNA) to enrich messenger RNA (mRNA) from mosquito gut samples for RNA sequencing (RNA-seq). The method utilizes sample-specific rRNA probes to effectively remove rRNA, achieving a depletion rate of approximately 90-99%.
