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
  • Ovary transplantation to rescue infertile 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
  • Embryo thawing to regenerate 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 index number or an off-campus purchase order
