The Mouse Transgenic Core Facility provides a series of high quality services related to mouse genetics, manipulation of mouse embryos, re-derivation and cryopreservation, and the stocking and distribution of shared mouse strains.

We have expertise in generating transgenic mice and gene targeted mice, and performs oocyte, morula, and blastocyst injections. The requesting investigator provides purified, prepared DNA constructs for transgenic injections.

Services Available

  • CRISPR/Cas technology to generate novel mouse models
  • CRISPR/Cas mediated genome modification in mice.
  • Cryopreservation program for mouse embryos and sperm
  • In vitro fertilization or embryo transplantation to recover mouse strains.
