What Biokit does

Biokit, doing business as Werfen Immunoassay, is a Barcelona-based contract developer and manufacturer of in vitro diagnostics (IVD) biomaterials and immunoassays, founded in 1973 and operating as a Center of Excellence within the Werfen group from its Lliçà d'Amunt facility. The company develops and manufactures custom antigens, antibodies, and immunoassays in bulk format for global IVD industry leaders, supported by an integrated end-to-end assay lifecycle service that spans bespoke reagent development, clinical studies, worldwide regulatory registration, and on-market product support. Beyond OEM biomaterials supply, Biokit markets a branded portfolio of diagnostic products targeted at blood banks and clinical laboratories.

The business model combines three revenue streams: project-based custom biomaterial development and manufacturing contracts with IVD OEMs (professional services), recurring bulk-format immunoassay supply agreements (subscription/recurring), and one-time branded product sales to blood banks and clinical laboratories. Pricing is quote-based and negotiated per project and is not publicly disclosed. Commercial reach is delivered through Werfen's direct sales offices in over 30 countries complemented by distributor networks covering more than 100 territories globally, supported by technical content marketing (technical notes, webinars, catalogs, blog, tradeshows) targeting IVD professionals.

The customer base comprises more than 60 long-term enterprise IVD relationships, with primary focus on diagnostic kit manufacturers requiring custom antibody and antigen production at scale. Biokit is positioned as a specialized outsource partner rather than a finished-assay brand, leveraging proprietary immunoassay know-how, regulatory expertise accumulated over five decades, and bulk manufacturing scale as its principal competitive advantages. No AI/ML capabilities, funding rounds, or independent management disclosures are present in the source data, and the unit operates within the privately held Werfen group.

Direct peers

• DiaSorin: Italy-headquartered IVD company focused on immunoassays and molecular diagnostics, with a similar European manufacturing heritage to Biokit. Overlaps directly in custom and bulk immunoassay reagent supply to clinical labs and IVD partners.
• Hytest: Specialist provider of monoclonal antibodies and antigens specifically for IVD manufacturers, with a similar custom development and bulk-supply model to Biokit. A directly comparable niche competitor serving global IVD reagent demand.
• GenScript: Global provider of custom antibody services, recombinant protein production, and IVD reagent supply with strong Asia-Pacific manufacturing scale. Directly comparable to Biokit in custom antibody/antigen development for IVD and life-science customers.
• Surmodics: Provides IVD reagents, antibodies, and biomaterials to diagnostic manufacturers, including custom development services. Comparable to Biokit as a focused supplier of immunoassay components to global IVD companies.
• Meridian Bioscience: US-based IVD company producing immunoassay reagents, antigens, and antibodies for diagnostic test manufacturers and clinical laboratories. Overlaps with Biokit in both IVD raw material supply and finished diagnostic test products.
• Bio-Rad Laboratories: Major diagnostics and life-science company with a portfolio of IVD reagents, immunoassay kits, and quality controls that competes for the same clinical lab and IVD manufacturer customers as Biokit. Bio-Rad also offers custom reagent services, making it a close functional peer in immunoassay supply.
• Fapon Biotech: China-based IVD raw-material supplier offering custom antibody and antigen development, bulk reagent manufacturing, and end-to-end IVD solutions. Closely comparable business model to Biokit, often positioned as a lower-cost alternative for global IVD manufacturers.

Broad incumbents

• Merck (MilliporeSigma): Operates one of the largest antibody, antigen, and bioreagent catalogs globally, including custom antibody development services. Competes with Biokit for IVD manufacturers sourcing high-quality antibodies and antigens, though Merck's portfolio spans the full life-science research and bioprocessing markets.
• Revvity (formerly PerkinElmer): Broad life-sciences and diagnostics company offering immunoassay reagents, custom antibody development, and IVD solutions across multiple modalities. Competitor in the IVD reagent supply space though not as specialized in IVD raw-material CDMO services as Biokit.
• Thermo Fisher Scientific: Global life-sciences leader with a substantial antibodies and immunoassay reagents catalog serving IVD and research customers. Overlaps with Biokit in bulk antibody/antigen supply, though Thermo Fisher operates across a much broader life-sciences portfolio rather than specializing in custom IVD reagent CDMO services.
