Next Generation Sequencing

Next generation sequencing technology has now reached tremendous throughput and accuracy that enable researchers to conduct large-scale genomic projects at affordable cost and in less time.

The NGS Platform of the Institut Curie has greatly evolved since 2012 mainly with the financial support of the ICGEx grant obtained in the frame of the EQUIPEX « investissement d’avenir » piloted by the ANR (ANR-10-EQPX-03). This grant allowed to purchase high throughput NGS sequencers, to fully equip a dedicated lab at the 7th floor of the hospital and expand the staff in charge of running sequencing projects.


  • Provide state of the art services in sequencing for the different research teams of the Institut Curie.
  • Offer technical and scientific support in experimental design and sequencing strategies.
  • Be flexible to best respond to scientific needs (technical development and implementation).


Under the supervision of Olivier Delattre and Alain Nicolas, the NGS platform provides state of the art services in sequencing. This includes the organization of pre-run meetings where the choice of the most appropriate technical strategy is defined in order to best address the biological question of collaborators. Multiple sequencing protocols have been developed and routinely used at the platform in order to cover most commonly used applications in genetics and epigenetics (Genome, Exome and targeted resequencing, RNA sequencing, ChIP-seq …). Furthermore, we are also willing to co-develop more specific protocols according to the need of research teams of the Institute.

Once the technical aspects are defined, samples are provided by collaborators and libraries compatible with the dedicated sequencing devices (Illumina or PacBio) are then prepared by the NGS team. After sequencing, raw data are transferred to the bioinformatics team (U900) for quality controls and basic analysis. At the end, sequence data are provided to research teams with comprehensive analysis and quality reports.

The platform is not restricted to fundamental research, we are also involved in multiple translational research projects in collaboration with U830, the translational research department and the Curie Hospital.
