Genetically Engineered Mouse Models for CNS Research & Development

CNS disorders have significant unmet medical needs for safe and effective treatments. The failure rate of CNS drugs in Phase 2 and Phase 3 clinical trials is approximately 85%. Many large pharmaceutical companies have ended their CNS research efforts because of the low success rate in developing new treatments. Innovative animal models that better represent human CNS disorders are essential to accelerating the identification of new targets and the development of new therapeutics.
GemPharmatech, a leader in genetically engineered mouse models, has several offerings that address this challenge.

Knockout All Project: KOAP

GemPharmatech is building a resource library of knockout (KO) and conditional knockout (CKO or floxed) models for the 22,000+ protein coding genes in the mouse genome using CRISPR-Cas9 technology and have completed more than 17,000 models to date. Existing models can be delivered in as little as 90 days and new models average 5-8 months for production.
GemPharmatech has extensive experience in gene editing technology and has established tens of thousands of gene-edited models utilizing CRISPR-Cas9, TALEN, ZFN, ES, and other technologies. We develop more than 6,000 new models each year and can work with you to develop custom mouse models to meet the needs of your unique development program. We guarantee that the models we develop meet specifications.

Preclinical Services

If you do not have preclinical research services in-house, GemPharmatech can provide an array of preclinical research services either directly or through our partners.
