Shared Resources

Transgenic Mouse


The Transgenic Mouse shared resource is a state-of-the-art facility that has an outstanding track record in the production of genetically altered mice. Transgenic mice carrying new or novel genes are created by microinjection of RNA and/or DNA into the pronuclei of fertilized eggs. Knock-out mice lacking specific genes of interest are created by homologous recombination in embryonic stem cells followed by injection into blastocysts to create chimeric mice. Highly experienced personnel produce transgenic , CRISPR , and knock-out mice for UC San Diego investigators at very reasonable cost and with very short lead times.  


Transgenic Mouse Shared Resource Services

  • CRISPR cytoplasmic or pronuclear injection of RNA/DNA to create transgenic mice
  • Pronuclear microinjection of DNA to create transgenic mice
  • Blastocyst microinjection of embryonic stem cells to create knockout mice.
  • Embryonic stem cell gene targeting for homologous recombination
  • Embryo rederivation to generate pathogen-free mice
  • Embryo freezing to archive existing mouse lines
  • In Vitro fertilization with frozen or fresh sperm to regenerate mouse lines
  • Sperm freezing to archive existing mouse lines

Where do I start?

So you want to make a transgenic or knockout line? Here's what you'll need to have before we can begin work on your project:

  • Approved animal protocol in place
  • DNA or RNA prepared using protocols provided by Core
  • Plan in place for screening ES cells (for KO)
  • Assigned animal space as destination for mice
  • Plan in place for screening pups
  • Trained personnel to breed mice, cut tails, and screen DNA
  • UC San Diego Chart String or an off-campus purchase order
