What Fortis Life Sciences does

Fortis Life Sciences is a private, US-domiciled life sciences reagents and diagnostics platform that aggregates multiple specialized brands under a unified 'One Fortis' umbrella. Its wholly-owned subsidiaries — Bethyl Laboratories (recombinant monoclonal antibodies), nanoComposix (engineered nanoparticles), Abcore (antibody development, VHH libraries), Vector Biolabs (viral vectors for gene delivery and CAR-T/CAR-NK research), Arista Biologicals (lateral flow infectious disease reagents), Empirical Bioscience (molecular biology enzymes and master mixes), and IPOC (life sciences reagents) — together supply antibodies, antigens, ELISA and Western Blot detection kits, IHC reagents, lateral flow components, nanoparticles, viral vectors, and VHH single-domain antibody libraries including the AbNano® platform.

The company monetizes through three streams: product sales (catalog research and diagnostic components), custom services (antibody development and manufacturing, viral vector services, diagnostic CDMO manufacturing, spatial biology multiplex imaging), and bulk/OEM supply for diagnostic kit manufacturers. Manufacturing and R&D are anchored in three ISO 13485-certified and GMP-compliant North American sites, with commercial reach delivered via a distributor network spanning 60+ countries across North America, South America, Europe, Asia, Africa, Oceania, and the Middle East.

Customers are organized across four vertical segments — research institutions, diagnostics manufacturers, biopharmaceutical companies, and applied technology companies — with pricing structured as quote-based B2B contracts across reagent SKUs, OEM partnerships, and service engagements. Differentiation rests on proprietary assets (AbNano® VHH libraries, 'Six Pillars of Antibody Validation'), the Farm-to-Bench integrated supply chain, regulatory certifications, and the consolidated multi-brand portfolio that lets customers source antibodies, nanoparticles, viral vectors, and diagnostic components from a single supplier.
