CRISPRnano: a new and easy-to-use webserver to identify genome edited cells

(Nanowerk News) Diseases of genetic cause can be investigated by inducing the respective mutations in cell lines that are then used to model human diseases. The overall aim is to elucidate underlying mechanisms, interactions with environmental factors and ideally to find curative strategies.
A crucial step in generating genetically modified cell models is to verify the inserted mutation. Therefore, the genetic information carrier of the cells is decoded (sequencing) and compared to the reference set of genetic information in healthy individuals (genotyping).
To support scientists with the comparison, different workflows and software are available, but many of them require expensive high-tier sequencers or manual curation efforts.
To address this issue, a team of scientists from the Genome Engineering and Model Development lab at the IUF – Leibniz Research Institute for Environmental Medicine in Düsseldorf, led by Dr. Andrea Rossi, developed a robust, versatile, and easy-to-use computational webserver named CRISPRnano that enables the analysis of noisy reads generated by affordable and portable sequencers including Oxford Nanopore Technologies (ONT) devices.
CRISPRnano allows fast and accurate identification, quantification, and visualization of genetically modified cell lines, it is compatible with Next Generation Sequencing (NGS) and ONT sequencing reads, and it can be used without an internet connection.
The related study was published in the scientific journal Nucleic Acids Research ("Identification of genome edited cells using CRISPRnano").
