Genome Engineering Zebrafish

National facility

The Zebrafish facility provides an infrastructure and individually tailored support for projects utilizing this popular model system for vertebrate development and disease. Zebrafish embryos are transparent and develop outside the mother’s body, which greatly facilitates manipulation and imaging of biological processes. The facility allows researchers to take advantage of the unique features of the zebrafish model system, and provides initial advice on feasibility and experimental design as well as running support over the course of the project.
