Cyagen’s HUGO-Ab™ fully human antibody mouse platform is designed to support therapeutic antibody discovery across a broad range of antibody drug formats, including monoclonal antibodies, bispecific and multispecific antibodies, antibody-drug conjugates, T-cell engagers, and fully human single-domain antibody candidates.
Rather than a single mouse model, the HUGO-Ab™ platform consists of three functionally differentiated product series: HUGO-Mab™, HUGO-Light™, and HUGO-Nano™. Together, they eliminate critical bottlenecks in biologic development, including candidate developability, heavy/light-chain mispairing, and the structural limitations of conventional IgGs.
Seamlessly integrated with our AI-powered AbSeek™ algorithms and in vivo efficacy models, HUGO-Ab™ accelerates your workflow from initial antigen strategy to IND-enabling translational evaluation.



Empowering High-Affinity, Fully Human Biologic Discovery
Developed via our proprietary TurboKnockout™ gene-editing technology, HUGO-Mab™ features precise in situ replacement of murine immunoglobulin variable regions with human repertoires.
Overcoming the Mispairing Bottleneck for Bispecific Therapeutics
HUGO-Light™ is specifically engineered to streamline complex multispecific formats. By inserting a pre-fixed, rearranged human light-chain variable sequence and inactivating endogenous light-chain genes, the model restricts immune responses to a shared common light chain.
Compact, Flexible, and Fully Human Single-Domain Solutions
Engineered for applications demanding compact molecular size and deep tissue penetration, HUGO-Nano™ directly generates fully human heavy-chain-only antibodies.
Breaking lmmune Tolerance for Highly Conserved Targets
For targets exhibiting high human-mouse sequence homology, immune tolerance often stifles antibody discovery. The HUGO-Ab-eKO™ platform swiftly knocks out the murine homolog on a fully human antibody background. By eliminating the endogenous antigen, it breaks immune tolerance.ensuring robust human-target recognition and high-titer responses against your most challenging therapeutic targets.
Cyagen delivers comprehensive in vitro efficacy validation services to enable rigorous evaluation of antibody binding kinetics, functional potency, immune effector functions, and species cross-reactivity. Leveraging our advanced cell engineering and reporter assay platforms, we provide the highly predictive data required to accelerate candidate prioritization and de-risk downstream preclinical development. To drive your therapeutic discovery, we offer a robust portfolio of engineered reporter cell lines and humanized cellular models derived from validated backgrounds (e.g., Jurkat, HEK293). These systems can be rapidly custom-engineered to express immune checkpoints, GPCRs, and metabolic targets, ensuring highly sensitive and mechanistically relevant functional readouts.
