A gene Knockin (KI) rat defines a model in which, by means of gene targeting, a gene sequence is inserted at a particular locus.
Since 2002, we have been heavily investing in rat model development (see our history), and have designed a unique CRISPR/Cas9-based offer, combining our:
- Expertise in model design
- Rigorous quality controls for rat models
With the advantages of gene CRISPR/Cas9 technology, such as:
- Cost effectiveness
- Short development time
Your benefits and guarantees:
- Robust design for physiological relevant rat models
- Reliable and reproducible performance in many rat strains, including, but not limited to:
- Inbred: Brown Norway, Fischer 344, Lewis, etc.
- Outbred: Wistar, Long-Evans, Spraque Dawley, etc.
- Freedom to operate thanks to our unique IP portfolio, including licenses from MIT and Merck KGaA
- Rigorous off-target assessment
Basically, two models are very common:
- Point mutation KI
One or more mutated nucleotides causing gain or loss of function of a given protein
- Quick Knockin
Controlled gene expression/copy number by targeting the permissive (neutral) locus Rosa26
