The GESR has implemented an innovative deadCas9 allelic sequestration CRISPR method that incorporates the use of nuclease deficient Cas9 (dCas9) to allow for modification of a single target allele. This method improves upon and allows for the use of CRISPR technology to modify a single allele in cases where modification of both alleles produce deleterious mutations, which could adversely affect the survival of the cell/embryo or alter stem cell properties through sustained DNA damage response.

The GESR offers the following services:

  • Mouse model generation includes any de novo mouse model production through CRISPR-Cas9 mediated gene editing or standard transgenesis. These include gene knockouts (KO), SNP knock-in (KI), epitope tag KI, and plasmid KI to express fluorescent proteins or Cre recombinase.
  • Cell line editing provides investigators with custom-modified KO or KI cell lines.
  • Mouse line cryopreservation is efficiently performed by sperm cryopreservation, except for mouse models containing several modified alleles which benefit from embryo cryopreservation to maintain their genetic composition.
  • Mouse line rederivation introduces new mouse models to the Cancer Center and tests the health status of existing lines.
  • The GESR supports the generation of expression and viral vectors for in vivo gene editing in their laboratory.
