AQRNA-seq for Quantifying Small RNAs

Overview

Absolute quantification RNA sequencing (AQRNA-seq) is a novel technology designed to quantify small RNAs in biological mixtures. This article demonstrates the library preparation and data processing steps of AQRNA-seq, focusing on the changes in the transfer RNA (tRNA) pool in Mycobacterium bovis BCG during starvation-induced dormancy.
