Zebrafish (Danio rerio) shares 87% genomic homology with humans. Its adaptive immune system such as IgH, TCR, MHC is structurally and functionally conserved, enabling V(D)J recombination, affinity maturation, and full antibody responses.
Traditional mouse/rabbit approaches fail because of their close evolutionary relationship to humans (~96 million years), causing immune tolerance for proteins with >85% homology. Moreover, multi‑spanning membrane proteins lose native conformation during recombinant expression, hiding critical epitopes.
Zebrafish mAb breaks three major barriers:
450 million years of divergence makes human proteins strongly immunogenic in zebrafish, breaking self‑tolerance.
Live‑animal immunization preserves native membrane orientation and post‑translational modifications, ideal for GPCRs/ion channels.
Only <50 μg antigen needed, enabling difficult‑to‑express targets.
Thousands of unique clones are readily obtainable with large library capacity, delivering far broader coverage of CDR space than hybridoma technology.
Up to 70% improvement in accessing hidden ECD epitopes recognizing conserved conformational epitopes missed by rodents.
Immunization-to-positive-clone screening is completed within weeks rather than months, drastically accelerating target validation.
Live‑animal immunization preserves membrane localization and PTMs, yielding antibodies with true biological relevance.
Empowering the entire value chain from drug R&D to diagnostic tools.
Rapidly generate high‑affinity lead antibodies against hard‑to‑drug targets (GPCRs, ion channels) for functional validation, in vivo efficacy studies, and subsequent humanization. Zebrafish‑derived CDR sequences offer differentiated IP space for better FTO positioning.
Provide sequence‑defined, batch‑to‑batch consistent recombinant monoclonal antibodies with strict epitope specificity and affinity fully compliant with IVD regulatory requirements.
Deliver high‑specificity tool antibodies for signaling pathway dissection, protein‑protein interaction studies, cell typing, and biomarker discovery finally overcoming the "can't find a good antibody" bottleneck.
<50 μg antigen and proprietary adjuvant, live‑animal immunization, preserving membrane protein conformation.
RNA from spleen/kidney, V‑gene amplification, phage display library (≥108 independent clones).
solid‑phase, liquid‑phase, or cell‑based panning to efficiently enrich clones against complex conformational epitopes.
scFv/Fab/IgG formats, ELISA, SPR, FACS multi‑dimensional verification.
