MicroRNAs (miRNAs) are small, non-coding RNA that play a critical role in regulating gene expressions that are important for a multitude of biological processes. In the preparation of miRNA sequencing libraries by using QIAseq miRNA library kit, adapter dimers might occur inadvertently and compromise the sequencing performance.

Covaris g-Tubes can be used to fragment DNA and are recommended for use in creating Oxford Nanopore (ONT) libraries. The volumes and DNA concentration typically used for ONT libraries are outside the range of the example data provided by Covaris. Here, we tested using the volumes and concentrations appropriate for our requirements.

Sarek: an open-source bioinformatic tool to detect germline variants and somatic mutations based on sequencing data from WGS, whole-exome sequencing (WES), or gene panels. Sarek offers easy, efficient, and reproducible analyses, and can readily be used both as a production workflow at sequencing facilities and as a powerful stand-alone tool for individual research groups.
