Sequencing Platform of Montpellier MGX GenomiX
Introduction
The facility was founded in 1999 when the Montpellier – Languedoc-Roussillon Genopole was set up. It is located on the Arnaud de Villeneuve campus, within the Functional Genomics Institute.
This platform offers the following services
- High-throughput sequencing
- Bio-statistics and bioinformatics
Applications available include de novo sequencing or re-sequencing of genomes, the study of the transcriptome of numerous animal, plant and prokaryotic species, but also techniques for studying chromatin structure and dynamics (ChIP-seq, 4C, Hi-C, etc.) and epigenetic modifications (DNA methylation). Genomic approaches on single cells in suspension or tissue sections are currently being developed.
The plateform is run by a team of 10 engineers: 7 molecular biologists and 3 bioinformaticians.
Expertise
The platform has developed solid expertise in “new generation sequencing” (NGS): Illumina and Oxford Nanopore technologies.
It also offers a complete service for the analysis of NGS data: identification of differentially expressed genes or transcripts, differentially methylated cytosines, enriched regions in ChIP-seq data, statistically significant variants… In addition functional contextualisation of the data can be performed
The platform is also able to develop custom protocols to meet specific needs and participates in the training of its users, both for library construction and data analysis.
The platform is currently exploring methods to limit sequencing costs and reduce biases related to library construction procedures, particularly in the context of transcriptomic studies.
Methods for assessing the stability of the genome of cell lines (particularly iPS) during the various steps of their growth are evaluated.
Equipments
- Sequencing : NovaSeq6000 sequencer 1 MiniSeq Illumina, 1 MinION Oxford Nanopore Technology
- 1 Chromium X 10X Genomics
- Automation : 2 Tecan Evo 150, 2 Mosquito HV
Development objectives
The platform is currently working on methods to limit sequencing costs and reduce the biases linked to library construction methods, particularly in the context of transcriptomic studies.
It is also working on a method for evaluating the stability of the genome of cell lines (particularly iPS) during the various passages necessary for their growth.
