CRISPR Rat Models
ingenious offers custom genetically modified rats, an exciting new option for your next genetically modified rodent model. Our unique technology delivers CRISPR rat models with unparallelled speed and accuracy by making targeted genetic modifications in spermatogonial stem cells. Placing modified cells into host rat guarantees germline transmission to rapidly establish your new line. This robust system provides a cost effective, scalable platform for the production of rats with enormous predictive power that will shape development of better therapies, pushing drug discovery research into a new era.
Get your custom rat model- in less time & with more certainty.
More Predictive Power
Germline In 3 Months
Enhanced Predictability & Speed of CRISPR Rat Models
Our advanced process enables genome editing directly within the rat’s germline. This allows for consistent and precise targeting, removes concerns and extra breeding due to mosaicism, and achieves germline transmission in three months versus six with traditional approaches.
What Types of Rat Models Are Possible?
The types of Custom Rat Models that are possible to produce are rat knockins that include a point mutation knockin, a knockin with reporter, an inducible/reversible knockin, and a Rosa26 rat knockin. Rat knockout models include a constitutive knockout and a conditional knockout.
Rat Point Mutation Knockin
Rosa26 Rat Knockin
Rat Knockin w/Reporter
Rat Inducible/Reversible KI
Constitutive Rat Knockout
Conditional Rat Knockout
Transgenic knockin rat models are powerful tools for research with many applications. Express one or more sequences throughout the animal or only in specific tissues. Common strategies include expression of mutated gene sequences, human gene sequences, and creation of tissue-specific reporter lines.
A custom knockout rat model from ingenious will support the research goals of your lab. A knockout line can model human disease, help understand a newly-discovered gene, and for drug discovery and development.

Why Rat Models?
Rats have been used to model human disease for over a century within a broad range of science fields including neurobiology, cardiology, immunology and toxicology. Their size and physiological similarity to humans make them an ideal choice for many labs. For example, surgical manipulations can be performed on rats that are difficult or impossible with smaller rodents, and fewer animals are required to generate sufficient material for experiments. Previously it was difficult to genetically modify rats but these limitations have been overcome by the use of CRISPR technology. Coupling CRISPR with our sperm stem cell technology takes this one step further, alleviating issues of consistency, predictability and mosaicism which are common when using CRISPR in embryos.

Understanding Rat Models of Various Human Disease
The Advantages of Rat Models
“We found iTL’s service to be exceptionally efficient and very well managed. We generated several mouse lines with iTL, and every step for each project was performed quickly and precisely, without any delays or problems.”
