TurboKnockout® Gene Targeting Mice Services

Cyagen’s proprietary TurboKnockout® gene targeting service is based on traditional embryonic stem cell (ESC)-mediated targeting techniques, which can be used for complex gene modeling projects to provide C57BL/6 or BALB/c mouse models in as fast as 6 months.

TurboKnockout® gene targeting eliminates the unpredictability of germline transmission (GLT) with a super competent ESC line that generates 100% ESC-derived founder mice rather than chimeras. Additionally, a self-removing selection cassette circumvents the need to breed to Flp deleter mice. For conditional knockouts, it may be possible to breed founders directly to your tissue-specific Cre mice. These innovations eliminate at least two generations of breeding, shortening production time by 4-6 months as compared to the industry standard.

Highlights of TurboKnockout® Gene Targeting
  • No patent risk: Technology of choice for drug development projects
  • Success rate: 100% guaranteed germline transmission (GLT)
  • Turnaround time: Founders as fast as 6-8 months
  • Size limitations: Knockin (KI) fragment size up to 200 kb
  • loxP restrictions: No size limitations for your floxed region
  • 100% Money-Back Guarantee on TurboKnockout® projects

BALB/c Strain Services Now Available

Over the last several years, Cyagen has tested numerous batches of BALB/c-strain ESCs for key characteristics – including progenicity, karyotype stability, totipotency, reproductive chimerism, and final germline chimerism - to identify BALB/c-derived ESCs suitable for generating targeted genetic models. In March, we announced the availability of BALB/c mouse models for all embryonic stem cell (ESC) based gene targeting services, including our proprietary TurboKnockout® technology.

Free Cyagen White Paper – Animal Models for Research

Cyagen’s model generation experts put together an exclusive White Paper, “Animal Models for Research - Choosing the Right Mouse Strains & Genetic Engineering Techniques,” that covers the key differences between C57BL/6 and BALB/c mice to consider when developing a mouse model for your research plan.

Covered Topics:
  • Comparing BALB/c and C57BL/6 Mice Strains Across Research Applications
  • BALB/c Strains Available for TurboKnockout® Embryonic Stem Cell (ESC) Mediated Services
