Rosa26 Knockin Mouse    

The Rosa26 locus on mouse chromosome 6 is often used to integrate transgenic structures to achieve ubiquitous or conditional gene expression in mice and is considered to be one of the ideal locations for knockin targeted genes. The DNA fragments placed at the Rosa26 site are very safe and stable. Using the classical gene targeting method, obtain a gene knockin mouse at Rosa26 always takes one year or more. With the application of CRISPR/Cas9-mediated knockin technology, large DNA fragments can be accurately and efficiently inserted into the Rosa26.

CRISPR/Cas9 PlatformCB, a professional gene-editing technology services company, has extensive experience in the application of CRISPR/Cas gene-editing technology and has successfully knocked out/knocked specific genes in >300 mice. We guarantee to provide you with at least 2 Founder mice or 3 F1 mice and complete them within 3-5 months.

Workflow of Conditional Knockout Mouse Services Using CRISPR and Cre/LoxP

  • Rosa26 Knockin Strategy Design

Based on the genes you are interested in, we will provide you with a comprehensive and efficient point mutation strategy to maximize Cas9 efficiency, including gRNA design and synthesis (target the sequence of the Rosa26 locus), donor vector construction, PCR primers for genotypic identification.

  • CRISPR Vector Construction

Synthesize gRNA, Cas9 mRNA in vitro, construct donor vector.

  • Injection into Mouse Embryos

gRNA, Cas9 mRNA and donor vector are simultaneously injected into single-cell mouse embryos. Typically, we will inject as many embryos as needed to fulfill the guarantee.

  • Genotyping of Founder Mice

Transfer healthy embryos to alternatives mother to produce founder mice. The Rosa26 locus sequence of founders will be detected by PCR and sequencing to reveal the insertion of genes your interest.

  • Breeding of Founders to Obtain F1 Mice

According to your needs, we will decide whether or not to breed the founder mice. Normally, we will breed up 3 founders which will be mated with wildtype mice of matched genetic background to generate their offspring. Then we will select F1 mice bearing targeted gene insertion at Rosa26 locus allele by genotyping.

Benefits

  • One-stop service from strategy design to F1 mice
  • Large-fragment DNA (<11Kb) at safe harbor location
  • Higher efficiency, faster turnaround and lower cost
  • F1 breeding to ensure germline transmission
  • Timely report on project progress
  • Tissue-specific/universal

Application

  • Study the functions of specific genes/proteins
  • Analysis of the role of non-coding regions and regulatory factors
  • Human disease model
  • Preclinical safety and toxicity studies
  • Drug screening and development
