    • Knockout Mouse Model Generation

      We can generate a gene knockout mouse model for inactivating genes either by frameshift mutation or by fragment excision, using CRISPR/Cas9. Gene knockout or disruption in mouse models provide an in vivo environment to study the function or role of the gene of interest. Applied StemCell has optimized and most-up-to date gene targeting strategies to generate the knockout mouse model of your choice. We can generate constitutive knockout mice or for a more advance study of the gene function, conditional/ inducible knockout models in as little as 5 months (F1 germline transmitted).

    • 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 (TARGATT™, TALENs and ZFNs). Applied StemCell offers knockin rat model generation using two technologies: CRISPR/Cas9 and TARGATT™ to enable the engineering a wide range of knockin modifications.
