Functional and Potency Bioassays with FyoniBio

Custom-Tailored Assay Design to Assess the Functionality of Your Drug Candidate

Whether you’re evaluating target binding, effector cell engagement, cytokine release, or cytotoxic responses, we develop physiologically relevant assays tailored to your molecule, study objectives, and regulatory needs.

Our Expertise in Functional and Potency Bioassays

At FyoniBio, we design and validate functional and potency bioassays that accurately measure your drug’s biological activity. Our expertise spans non-cellular and complex cell-based formats, supporting biotherapeutics from antibodies to oligonucleotides. Optimized for preclinical and clinical studies, our assays ensure relevance, reproducibility, and clarity throughout development.

Designed for a Broad Range of Biotherapeutics and Indications

Our assay portfolio supports a wide variety of therapeutic modalities—from small oligonucleotides to complex biologics like monoclonal antibodies and fusion proteins. These assays are applicable across multiple disease areas, including:

Let’s Advance Your Biologic Together

Your Molecule Is Unique. So Is Our Approach.

We design tailored assays that reflect your therapeutic’s biology and development goals,
because one-size-fits-all doesn’t work in drug development. Let’s build the right assay, together.

Our Cell-Based Assay Capabilities

Functional bioassays are essential for understanding the biological activity, quality, and safety of your therapeutic by evaluating its effects within a biological system. Cell-based assays offer distinct advantages (especially for multi-domain or multi-functional proteins) over conventional immunoassays:

› Preserve native protein conformation

› Recreate multicellular environments, enabling interactions within complex cellular networks

› Enable dynamic readouts of downstream signaling pathways

Comprehensive Mammalian Cell Culture Services

  • Immortalized cell line maintenance and expansion
  • Primary cell isolation, differentiation and cultivation ​
  • 3D spheroid model generation
  • Stable cell line creation for disease modeling or effector function
  • Cryopreserved cell line inventory management

With access to a broad panel of over 130 human and animal cell lines, we can match the right cellular system to your assay requirements, or seamlessly integrate a preferred cell line you’ve already selected. If you have an established assay or proprietary model, our team can transfer and optimize it within our facility, ensuring continuity, precision, and regulatory alignment from the very start.
