Zebrafish (Danio rerio) are widely used as a model organism in developmental biology, immunology, genetics, and drug discovery due to their transparent embryos, genetic tractability, and conserved vertebrate biology. However, their small size and limited blood yield present significant challenges for conventional monoclonal antibody (mAb) generation.
At Creative Biolabs, we've addressed these obstacles by developing a specialized discovery workflow that integrates phage display antibody library construction with microscale-compatible molecular biology methods. This platform enables the generation of high-quality zebrafish-specific antibodies that are particularly useful in applications such as lineage tracing, in vivo imaging, cell-type–specific detection, and validation of genetically modified lines. Our service is especially suited for research institutions and diagnostic developers working within zebrafish-based systems.
Creative Biolabs' Zebrafish Monoclonal Antibody Discovery Service provides a fully integrated workflow that begins with rational antigen design and ends with delivery of sequence-defined, functional recombinant antibodies. From small-volume-compatible immunization strategies to high-complexity phage display library construction, every step is optimized for zebrafish biology. We provide support for recombinant antigen preparation and immunogen formulation, RNA extraction from pooled animals or specific tissues, phage display screening against your antigen of interest, antibody sequence recovery, and recombinant expression in your preferred format. Additional services such as epitope mapping, fluorescent labeling, and antibody reformatting are also available to suit your research or diagnostic applications.

Creative Biolabs leverages our extensive experience with diverse host species to tackle varied project goals and immunogenicity challenges. Our species selection is rooted in scientific rationale. While we excel in zebrafish, we also boast a proven track record of successful monoclonal antibody development from numerous other hosts, highlighting our flexibility and broad expertise. This ensures your zebrafish mAb discovery benefits from both innovative approaches and a history of success.
A: Ideal targets include transgenic markers, zebrafish-specific surface proteins, fluorescent protein tags, and lineage or tissue-specific cell markers.
A: Yes. We routinely work with pooled fish to extract enough B-cell RNA for high-complexity library construction.
A: Yes. We offer endotoxin-free antibody prep and can deliver scFv-Fc or fluorescently labeled formats.
A: Yes. If you have antigen or sequence data for a zebrafish protein, Creative Biolabs can initiate a mAb project using synthetic peptides or recombinant constructs.
