For more than 25 years, ingenious targeting laboratory has supported biomedical research with animal models that provide stable allele designs, reproducible cohorts, C57BL/6 backgrounds, and U.S.-based QC oversight. Each project follows an evidence-based, results-driven approach to deliver animal models with reliable inheritance and long-term performance.
Across today's research environment, scientists utilize a wide array of genome-modification technologies, including programmable nucleases, rapid-editing strategies, exploratory one-cell–stage modifications, and other contemporary editing systems used throughout the field. These approaches and others are discussed with an emphasis on structured allele design, stable inheritance, and multi-generational reproducibility for long-term performance aligned with your specific study requirements.
We evaluate all available genome engineering technologies to determine the best method for your specific research goals. Technology selection is based on allele complexity, stability requirements, and reproducibility standards.
Each stage of custom development—allele confirmation, germline transmission, colony establishment, and cohort expansion—is validated through U.S.-based QC. This comprehensive oversight ensures consistent quality and reliable results across all project phases.
The C57BL/6 background ensures reproducibility across cohorts, replicates, and multi-site studies to eliminate confounding variables and support consistent phenotypic outcomes.
Allele designs are chosen to support reliable and consistent performance across downstream assays. This includes constitutive knockout, conditional knockout, reporter gene insertion, knock-in (point mutation, cDNA), and humanization projects, all designed to maintain stable inheritance and interpretable outcomes across generations.

Our systematic approach ensures consistent results from project initiation through delivery of study-ready cohorts:
Free scientific consultation to review experimental goals, recommend optimal targeting strategies, and provide timeline and pricing estimates.
Custom allele design development based on your research requirements, including selection of appropriate targeting approach and cassette configuration.
Design and synthesis of targeting materials, including sequence verification and quality control.
Injection and breeding of F0s to achieve germline transmission.
Study-ready cohort expansion with structured breeding for statistical power.

“ingenious Targeting Laboratory is highly recommended for generating custom animal models. Past 2 years, we have made 2 conditional knockout mouse lines. All processes of each project were scientifically and professionally handled. Their scientific consulting to initiate the project was superb compared to other companies, and transparency of the project progress reported by project managers was excellent. Their excellency and dedication to meet our needs in a timely manner are invaluable to continuation of our research progress.”

“iTL produced a new conditional mouse model for us and the quality of service was exceptional. The team is extremely knowledgeable and the work was completed at the highest possible standards. My project manager was excellent and always happy to answer technical questions and keep me up to date with progress and potential problems. I would recommend iTL highly and will use them again in the future if I need to generate a new mouse line.”
