Core Description

The Mouse Gene Manipulation Core centralizes the production of genetically altered mice for IDDRC investigators in a cost-effective and efficient manner. The Core also provides expert assistance in the additional areas required for generating genetically altered mice, including transgene and targeting construct production, and transgenic mouse colony management. Core personnel are available to train investigators in all of the techniques required for the generation of genetically modified mice.

  • Genome editing in vivo using CRISPR/Cas9
  • Transgenic DNA microinjection
  • Gene targeting by homologous recombination
  • Blastocyst injection to produce chimeric mice
  • Cryopreservation of mouse strains
  • Rederivation by IVF and embryos transfer
  • Derivation of ES cell line from mutant strain
  • Genotyping founders by Southern blot
