The NGS platform provides I-Stem with high throughput genome and/or transcriptome sequencing services as well as scientific and technical support to propose the most suitable sequencing strategies for the projects
DNA sequencing, and more particularly high throughput sequencing, is a technology that allows us to study and better understand the rare genetic diseases on which we work at I-Stem. Depending on the techniques developed, it is possible to search for new mutations responsible for genetic diseases (DNAseq ) or to study the expression of genes in a healthy and/or pathological context (RNAseq – transcriptome study). At the end of the bioinformatics analysis, these data can lead to the identification of new therapeutic targets.
The platform has a NextSeq 550 Illumina sequencer as well as equipment for sample extraction, quantification and quality control (Qiacube – Qiagen / BioAnalyzer – Agilent / QuantStudio 12K & 7K – Thermo Fisher Scientific). Since 2020, the platform also offers single cell sequencing (Single cell RNAseq – Chromium 10X genomics)
In addition to the service activity, the platform conducts R&D programs such as the development of new sequencing techniques or new bioinformatics tools (databases, NGS analysis pipelines, etc.)
