Sequencing platform GenomiqueENS
Introduction
The GenomiqueENS core facility is affiliated to École normale supérieure (ENS), CNRS, INSERM, and located in Paris within the Institut de Biologie de l’École normale supérieure (IBENS). Created in1998, it aims at:
1) To make functional genomics technologies available to public sector research laboratories,
2) To assist researchers to manage their high-throughput genomics projects,
3) To widely disseminate the approaches across the scientific community.
With 7 staff members (5.2 ETP), we have the capacity to support around 70 projects per year from the definition of the experimental design to the analysis and publication of the results.
Expertise
The facility supports its collaborators by providing access to high-throughput sequencing, with particular expertise in functional genomics applications in eukaryotes :
• Transcriptomics: RNA-seq (low input, long-read, single-cell, direct RNA)
• Epigenomics/Epitranscriptomics: ChIP-seq, RNA m6A methylation
• We have a particular expertise in Nanopore long-read sequencing for transcriptomics, including for single-cell RNA-seq.
We also propose a sequencing service “ready-to-load” for users who make their own libraries.
Equipment
- Sequencing (short reads): NextSeq 2000 (Illumina)
- Sequencing (long reads): PromethION P2solo, MinION and MinION Mk1C (Oxford Nanopore Technologies)
- Single-cell transcriptomics: Chromium Controller iX (10x genomics)

Bioinformatics
- Bioinformatics analysis: for collaborative projects sequenced in our facility we perform quality controls, RNA-seq differential analyses (including complex designs) on Illumina and Nanopore datasets, isoform identification (Nanopore), and single-cell RNA-seq (Illumina and Nanopore)

Main achievements
Our platform hosts medium-sized projects (around ten samples per project) on a varied number of model or non-model eukaryotic species (more than twenty currently ranging from fungi to mammals) with topics mainly related to development, neuroscience and genetic regulation. The projects we take on are very often limited in terms of the quantity of starting material and we have now developed a real expertise in the management of this type of studies.
We also have a bioinformatics tool development activity focused on the analysis and automated quality control of the projects we process. We have developed innovative solutions (Eoulsan, Aozan and ToulligQC) using calculation distribution tools (cloud computing, MapReduce, Hadoop), traceability and source code availability (GitHub and Docker).

Certification / Quality Assurance
We are fully committed to the ISO 9001 quality management system and obtained our first certification in April 2013, completed by the validation of the NF X50-900 standard in April 2016. Certifications have been renewed in 2019.
Labels
The platform was labelled successively RIO-RNG from 2002 to 2007 and then was IBiSA certified since 2008
