Custom Model Generation

Custom Model Generation

Let us design your ideal animal model with our custom model generation service


Looking for a CRISPR mouse or rat model not included in our existing model catalog?

Horizon Discovery's in vivo custom model generation specialists can work with you to design and deliver a genetically engineered animal model to your exact specifications, using our CRISPR-Cas9* or Zinc Finger Nuclease technologies**, in as few as 4 months.

Beyond constitutive gene knockouts, we offer more sophisticated project types - humanized, conditional knockouts, point mutations and reporter tagging.

Animal Research Models of Human Disease

As CRISPR-Cas9 and ZFN technologies directly enable targeted mutagenesis at the single cell stage, embryonic stem cells are not required - making custom model generation much faster and without background strain limitations.

These technologies are utilized to generate sequence-specific double-strand breaks that are repaired by error-prone Non-Homologous End Joining (NHEJ) or high-fidelity homologous recombination (HR).
