TACGENE was created in 2011 within the U1154-UMR7196, to facilitate access of academic laboratories to genome editing techniques. Supported under the National Project "Investissement d'Avenir" - National Infrastructures in Biology Health TEFOR (that stands for Transgenesis for Functional Studies on Model Organisms in English), we have developed a strong expertise in the design, production and use of TALEN (transcriptional Activated Effector like Nucleases) and CRISPR (clustered interspaced short palindromic Regularly repeat) / Cas.9 technologies. We use them in cell culture in our research projects and in collaboration in many model organisms, particularly rats, mice and zebrafish thanks to the Celphedia  Network.

The activities of research and development we carry out in GE2R team to improve these technologies, in parallel to TACGENE service activities enable us to offer advanced solutions and expertise on the various issues of genome editing (knock-out, knock-in ...) currently available.
