Applied StemCell’s comprehensive CRISPR mouse generation service platform uses upgraded designing strategies, highly optimized, ISO:9001 QMS-certified CRISPR protocols and validation methods to generate mouse models successfully with a fast turnaround and reduced cost.

  • Frameshift mutation or targeted deletion
  • High efficiency gRNA for ~100% Cas9 target cutting efficiency
  • F1 breeding to confirm germline transmission
  • Dedicated project management and timely milestone and final reports


  • CRISPR Vector construction: gRNA design, validation, donor DNA construction (if needed), in vitro transcription and QC for Microinjection
  • Pronuclear injection and embryo transfer
  • Genotyping of offspring for integration, animal care and housing
  • Recommended: F1 Breeding of founders for germline transmission

Timeline: 3-5 months


  • At least 2 founders (or germline transmitted F1s) with confirmed gene knockout
  • Milestone update/report; final report with detailed description of each procedure, including targeting vector design, construction and validation, transfection condition, genotyping strategy, and results.


  • Study role of genes and proteins
  • Disease modeling
  • Validate drug targets and specificities
  • Genomic validation for antibodies
  • Immuno-oncology research and drug discovery
  • Preclinical safety and toxicity studies

For knockout of essential gene, ASC offers PrimeCKO™ Conditional Knockout Mouse Model Generation service.
