Shared Resources

The Gene Targeting Core Facility was established in 2016 and supports the Moffitt Research Community with the production of genetically engineered mouse models. The facility is managed by Jose Gonzalez who has more than 20 years of experience in generating transgenic animals. 

The goal of the facility is to offer a streamlined, efficient, and affordable array of state-of-the-art transgenic approaches to create cancer mouse models for in vivo biological and preclinical studies.

The facility is located in the vivarium in the Stabile Research Building, where it occupies two adjacent rooms for embryo manipulation and housing of animals. This assures the highest success of transgenic mouse production, eliminates the need for quarantine, and allows for easy transfer of transgenic mice to the investigators. In addition, the Gene Targeting Core Facility performs murine embryonic stem cell work, both derivation of new cell lines and gene targeting, in a dedicated cell culture room.
