About Us

Recombinetics is a recognized leader in gene editing to advance human and farm animal health and welfare.

Founded in 2008, Recombinetics is a privately held biotechnology company that aims at helping to solve some of the world’s most intractable challenges through gene editing. Recombinetics is delivering viable products and generating revenues today from the large and growing biomedical and agricultural markets.

Recombinetics focused its early-stage development on the application of precision genetic technologies and active patent filings in animals. Development of advanced “gene-editing” technologies for commercial purposes began in 2011. Today, Recombinetics is widely recognized as the leader in livestock gene-editing and associated applied technologies for biomedical research, regenerative medicine, and animal agriculture.

Recombinetics’ first gene-edited animals are generating revenues today with a pipeline of animals under development for the large biomedical and agricultural markets.

Company Firsts

Recombinetics is a company built on firsts.

With a robust intellectual property portfolio, RCI leverages its research platform to commercialize and deploy its invented and licensed technologies across key markets.

RCI’s growing global patent portfolio includes 33 issued patents, more than 170 additional applications filed, and first use and enabling patents for livestock for both CRISPR and TALENs.
