Cytometry Facility


Flow Cytometry Platform


The Cytometry Platform (acronym BV-CyAn) has been created in 2012 to provide access and develop this technology to the iBV research groups and is open to outside investigators. It offers a range of services centered on multiparametric cytometry and cell sorting.

BV-CyAn platform, by offering state-of-the-art flow cytometers and sorters, proposes to researchers, powerful ways to discriminate, analyse and sort/purify the distinct cell/organelle populations of interest to further study the genomic, proteomic and functional aspects of such purified populations.


  • Provide access to cytometer users of the platform.
  • Teaching (users quickly become autonomous and independent in the use of analyzers), assistance (in the design of experiments, in the analysis, interpretation and presentation of results) and expertise.
  • Cell sorting: provide technological development with new technical achievements.
  • Single Cell Profiling: “Single cell analysis“ allows studying the transcriptomic and/or epigenetic content of tens of thousands of cells one by one. The cytometry platform takes care of your samples (cells in suspension or obtained via FAC-sorting), performs cell encapsulation and barcoding, and prepares the libraries required for next generation sequencing.

Chromium Controller (10x Genomics)

This equipment is used to prepare gel bead emulsions that permits the encapsulation of individual cells in a lipid droplet (GEM) allowing to assign a unique identifier to each cell (called Barcode). In addition, each transcript of a cell is tagged with a molecular identifier “UMI”. The single cell transcriptome provides a high-resolution description of the cell content.

Application Areas:

  • Single cell RNA gene expression profiling
  • Single cell chromatin profiling
  • Rare cell type detection
  • Tumor heterogeneity
  • Mechanisms of cellular differentiation
