    • Human ACE2 Mice for COVID-19 Research


      Humanized ACE2 Mouse Models Available Now

      To aid the global research efforts to find a solution to the COVID-19 pandemic, Applied StemCell has leveraged its site-specific TARGATT™ knockin technology to engineer two fully humanized ACE2 (hACE2) mouse models with lung epithelium-specific expression driven by the K18 promoter. These TARGATT™ hACE2 mouse models have the K18-hACE2 transgene integrated into a preselected, well-characterized safe harbor locus (genomic hotspots): mH11 or mRosa26 and might be more representative to model the severity of the SARS-CoV-2 infection. The TARGATT™ hACE2 mouse models are ideal to help understand the severe pathogenesis of COVID-19, and to evaluate the efficacy of antiviral drugs and vaccines.

    • Knockin Rat Model Generation


      Rat models are very important models for specialized research where mouse models are not quite representative of the human physiology or behavior. Like mouse models, targeted genetic engineering in rat models has been revolutionized with CRISPR/Cas9 and other technologies (TALENs and ZFNs). Applied StemCell offers knockin rat model generation using CRISPR/Cas9.

      • Highly optimized and efficient protocols
      • High-efficiency gRNA for high Cas9 target cutting efficiency

      • F1 breeding to confirm germline transmission
      • Dedicated project management and timely milestone and final reports
    • Point Mutation Rat Model Generation


      Point mutation mouse models are generated by inserting or replacing in one or more variant nucleotides in selected gene(s). These models are very important to study the importance of specific nucleotides or amino acids in gene expression or protein function and for disease modeling. As one of the earliest providers of CRISPR-based custom mouse model generation services, Applied StemCell can generate defined constitutive or conditional point mutation knock-in models using CRISPR/Cas9. We can generate your point mutation founders/ F1 germline transmitted animals using our optimized and efficient protocols, with a high success rate. All mouse models are generated in our facilities under AAALAC accreditation and IACUC oversight. We can also ship animals worldwide or as cryopreserved embryos.

      • Highly optimized and efficient protocols
      • High-efficiency gRNA for high Cas9 target cutting efficiency
      • In vivo gRNA validation 
      • F1 breeding to confirm germline transmission
      • Dedicated project management and timely milestone and final reports
    • Bacterial Artificial Chromosome (BAC) Knock-in and Conditional Knock-In Rat Models


      Bacterial Artificial Chromosomes (BACs) are ultra-low copy vectors that can hold up to 300 kb of genomic fragments, making them ideal vectors for the introduction of entire genes including the regulatory regions into the rat genome. BAC transgenic rats are similar to other knock-in models in the expression pattern of the gene of interest, except that the BAC is randomly integrated into the genome as a transgene. Applied StemCell can create BAC knock-in and conditional knock-in rat models for you.

      Our services include:

      • BAC design and cloning strategy
      • Cloning and sequence validation of the BAC tailor-made to your specifications
      • Pronuclear microinjection of BAC into rat embryos
      • Genotyping

      Alternatively, you can choose to have us do the BAC modification strategy and cloning, and you can do the pronuclear injections and transgenic rat screening yourself.
