Transgenic & Gene Targeting Mouse Core Facility

The Transgenic & Gene Targeting (TG) Mouse Core Facility provides state of the art services to generate genetically modified mouse research models. The TG Mouse core uses CRISPR technology to generate knockout, knockin, and conditionally targeted alleles in mice. This method allows for the efficient and relatively inexpensive generation of mice with specific genetic mutations. Other services include conventional targeting of mouse ESCs, injection of ESCs to make germline chimeras, and production of traditional transgenic mice using random genomic insertion methods. In addition to producing novel mouse models, the TG Mouse core provides services for common mouse procedures including embryo and sperm cryopreservation, in vitro fertilization (IVF), karyotyping of ESCs, rederivation of mice from frozen embryos and derivation of primary mouse ESCs. 

The TG Mouse core staff works closely with University of Utah regulatory groups and is in compliance with strict IACUC and USDA guidelines.

Generation of Genetically Modified Mouse Lines

Pronuclear InjectionF1$4,950Implantation of >200 injected embryos
Embryo ElectroporationF1$2,200Implantation of >125 electroporated embryos
Validation of CRIPSR reagents (per condition)F1$220>50 electroporated embryos
CRISPR ESC Targeting F1$3,150192 clones from CRISPR edited population 
Traditional ESC TargetingF1$5,400192 selected clones
Blastocyst Injection F1$6,000>2 chimeras 
Breeding to N1 generation NA$495Outcrossing of 4 founder mice
 Service fees include the purchase of donor female mice, superovulation, microinjection, microsurgery procedures, ear tissue collection for DNA isolation and animal housing up until weaning. Users will be charged cage per diems for mice that remain in the core post weaning.  These fees do not include CRISPR reagents, transgenic constructs, genotyping, and DNA sequencing. The Mutation Generation and Detection (MGD) Core provides these molecular services or users can also supply their own reagent for injection.  The total cost to generate a novel mouse model from start to the sequenced heterozygous N1 generation is $9,000-$12,000 and depends on the mouse strain and edit type. 


Rederivation of frozen embryosC57BL/6J$880Minimum of 2 carriers

To recover a frozen line please email the core director to coordinate the transfer of the frozen sperm, embryos or ESCs to the core. Users are welcome to ship samples directly to the core.
