Analytical Characterization Services for Biologics & Biosimilars

Biofidus is your bioanalytical laboratory of choice for fast, reliable analytical services for biologics and biosimilars, from early discovery through preclinical and clinical development. We support start-ups, biotechs and big pharma across the entire biologic development cycle, including cell and gene therapeutics, with a strong focus on CMC and regulatory expectations.

Our mission is to accelerate your development by providing tailored, in-depth characterization of your biopharmaceutical product and by helping you ask, and answer, the right CMC questions for agencies such as FDA and EMA. We design analytical programs around critical quality attributes (CQAs) that define identity, purity, potency, safety and stability, always following the principle: As much as necessary, as little as possible.

Drawing on decades of combined experience in mass spectrometry, chromatography, sequencing, electrophoresis and cell-based assays, our team has worked on hundreds of biologics and biosimilars projects. From routine high-throughput analysis to complex comparability and biosimilarity studies, we build fit-for-purpose, regulator-ready analytical packages that de-risk your CMC strategy, process changes and lifecycle management.

Core Capabilities

  • Identity, primary structure & sequence integrity (intact MS, LC-MS/MS peptide mapping)
  • Glycosylation & Post-translational modifications (PTMs) (HILIC-FLD/LC-MS, LC-MS/MS peptide mapping)
  • Size variants & aggregation (SEC-UV/SEC-MALS, DLS, CE-SDS)
  • Charge variants & isoforms (CEX-HPLC, icIEF, CZE)
  • Impurities & process-related contaminants (HCPs, residual DNA)
  • Biological potency & functional activity (custom cell-based assays, ELISA)
  • Target binding, affinity & kinetics (SPR, binding ELISA)

FAQ

Find answers to frequently asked questions about our analytical services, methods, technologies, and studies, from molecular characterization and bioactivity to comparability, stability, and fit-for-purpose method development. 

Yes. We support method development and fit-for-purpose qualification/transfer to match the stage and intended use, enabling regulator-ready documentation for CMC programs.

Yes. At Biofidus, we not only apply established platform methods but also actively develop and adapt analytical methods tailored to your specific molecule, matrix, and development stage.

Yes. Where relevant, we integrate impurity testing into broader analytical packages, supporting quality control strategies for NBEs and biosimilars.

Yes. We build comparability panels around CQAs most sensitive to process and formulation changes and deliver fit-for-purpose, regulator-ready data packages for CMC decision-making.

A typical core panel covers identity/primary structure (intact MS, LC‑MS/MS peptide mapping), glycosylation/PTMs (HILIC‑FLD/LC‑MS), size/aggregation (SEC‑UV/SEC‑MALS, CE‑SDS), charge variants (CEX-HPLC, icIEF/CZE), plus binding/potency (SPR, ELISA, cell-based assays) as needed.
