PHENO-ZFish : zebrafish experimentation service

Ouvrir / fermer le sommaire
This service is dedicated to pre-clinical research on zebrafish. With more than 20,000 adult fishes capacity and high quality equipment such as the automated feeding robot, 6 injectors for transgenesis users combine imaging, optogenetics, behavioral experiments on mutant and transgenic lines. External partners have access to specific training sessions such as fish manipulation (crossing, eggs collection), transgenesis, screening and sperm freezing. Highly skilled technicians are in charge of fish care, crosses and health monitoring. PHENO-ZFish is part of the Institut du Cerveau – ICM core facility network (vectorology, genotyping sequencing, cell culture, electrophysiology…) which facilitates translational research projects.
