Transgenic Knockout Mouse

About the Transgenic/Knockout Mouse Shared Resource (TGKO)

Genetically engineered mouse models (GEMMs) have become indispensable tools in nearly all fields of biomedical research. For example, in cancer research their utility ranges from studies of the basic biology of tumorigenesis and progression to the creation of genetically accurate tumor models for the evaluation of novel therapeutic approaches. The objectives of TGKO are to:

Facilitate the development of new GEMMs (including transgenic, knockout, conditional knockout and knock-in mice) using both conventional and CRISPR/Cas9-based technologies
Provide a full range of support services to facilitate the use of these models, including breeding colony management, mouse line rederivation, embryo and sperm cryopreservation and cryorecovery
Offer expert consultation on the development and use of GEMMs

Equipment
The Transgenic/Knockout Mouse facility is located on the 8th floor of the Molecular Medicine Research Building (MMRB). It occupies a 1,000-sq-ft suite that includes a 600-sq-ft laboratory, 150-sq-ft tissue culture room, and a 250-sq-ft animal holding room dedicated for mice related to GEMM production. Two additional 450-sq-ft holding rooms in MMRB are dedicated to housing mice in the breeding colony management program. A 150-sq-ft holding room in Sanger Hall is dedicated to holding mouse lines undergoing rederivation by the Transgenic/Knockout Mouse core.

The laboratory is equipped with:
- Olympus IX-71 inverted injection scope with stage cooler (for microinjection)
- Two Eppendorf TransferMan 4r micromanipulators
- Eppendorf Femtojet 4i microinjector
- NEPAGENE NEPA21 electroporator
- Olympus DP-72 Digital Camera
- Vibroplane air table
- Nikon SMZ-800 dual-head teaching microscope (for mouse surgery)

- Thermo LN₂dry shipping unit
- Marathon refrigerated centrifuge
- Nikon Eclipse TS100 inverted scope (for cell culture)
The molecular biology work associated with mouse production is carried out in Dr. Windle’s lab on the 7th floor of MMRB, which is fully equipped for molecular biological studies.

The core also maintains an IVIS Spectrum II optical imager in the MMRB vivarium. Please contact Greg Campbell at gecampbell@vcu.edu or (804) 827-3974 for training and access to the imager.
