Our Transgenics services are available to the wider biomedical community. We provide a specialist service for the generation of new mouse models, as well as all aspects of cryopreservation and re-derivation of established lines.

Working closely with the Genome Engineering team, we offer expert advice on the generation of new mouse models, covering the initial targeting strategy and design of targeting constructs to the preparation of material (DNA, RNA proteins etc) for microinjection. We also advise on the most appropriate way to cryopreserve mouse lines.

All of our work is carried out under the authority of a Home Office project licence (PPL). New mouse models are produced under this PPL and are then transferred to the authority of the end user's licence for further breeding.
