    Modular IgA Scaffolds for Versatile Therapeutic Applications

    At Creative Biolabs, we offer a cutting-edge IgA-Based Seed Body Production Service, designed to provide a modular platform for the development of IgA-based therapeutics. Our seed bodies serve as a foundation for creating customized bispecific antibodies, fusion proteins, and antibody-drug conjugates (ADCs).

    The service supports rapid development and tailored customization of IgA-based biologics, preserving mucosal immunity while also optimizing for features like extended serum half-life and multispecific targeting.

    Service Highlights

    Seed Body Design
    • IgA1 and IgA2 frameworks with FcαRI-binding for enhanced effector function.
    • Optional IgG Fc integration or FcRn-binding motifs for extended half-life.
    • Customizable to meet specific mucosal or systemic targeting needs.
    Modular Engineering for Customization
    • Multispecific formats: Easily incorporate additional binding domains to create bispecific or trifunctional antibodies.
    • Fusion protein design: Integrate additional domains for targeted therapies or immune cell engagement.
    High-Yield Expression & Purification
    • Express seed bodies in CHO or HEK293 cells for high-yield, consistent production.
    • Purification via affinity chromatography (Protein A/G/L) to ensure high-purity and functional protein.
    Functional and Biophysical Testing
    • FcαRI binding assays and pIgR-mediated transport to validate mucosal targeting and immunological activity.
    • Glycosylation analysis and stability profiling to ensure reproducibility and robustness.

    Advantages of Our Service

    • Scaffold Flexibility: Create multispecific antibodies or ADCs from a single IgA scaffold.
    • Rapid Customization: Quickly adapt to different therapeutic formats with a modular approach.
    • Mucosal Immunity Preservation: Maintain key IgA properties such as FcαRI binding and polymeric structure.
    • Scalable Production: Achieve high-yield production for research purposes.
