Combining GENOVAC Antibody Technology with Ligand’s OmniAb™ transgenic rodents provides clients with accelerated discovery, in vivo optimization for therapeutic efficacy and manufacturability, and fully human sequences for safety and reduced immunogenicity.

A variety of immunization protocols have been applied successfully with OmniAb animals, including DNA, peptide, protein, or cell immunization.The technology also has been used to complete multiple projects with OmniRat™, OmniFlic™ and OmniMouse™ antibody platforms. 

By establishing a collaborative workflow between the end user, Ligand and the breeding facility, GENOVAC can take a project from a target sequence to immunization, fusion, screening and delivery of the desired antibody.

Case Studies

Epitope coverage

Objective: Generate a diverse panel of mAbs specific for different members of the human CEACAM family in the OmniRat Antibody Platform.

Target: Human CEACAM5

Method: Genetic Immunization of OmniRats

CEACAM comparison chart

Table of CEACAM comparisons

Result: Similar epitope coverage of cross-reactive mAbs with OmniRats and Wistar

T-Cell Receptor (TCR) complex

Objective: Generating monoclonal antibodies using the OmniRat Antibody Platform against the human TCR-complex with cross reactivity to the Cynomolgus TCR-complex.

Method: Genetic immunization of OmniRats by co-immunization with CD3 chains

TCR-complex diagram

The TCR–complex is composed of 6 different polypeptides on the surface of T-cells:

  • alpha & beta fragments
  • CD3 gamma, delta, epsilon
  • Zeta chains


OmniAb Strains vs. Target Classes

OmniRats Kappa & Lambda: Ligand-Receptor Protein Complex
