What Affinity Biosciences does
Affinity Biosciences is a privately held life-sciences reagent supplier founded in 2006 and headquartered in Cincinnati, Ohio, with its primary legal entity (Affinity BioSciences Group LTD.) incorporated in the United Kingdom. The company designs, produces, and distributes antibodies, inhibitors, SiRNA products, kits, and custom synthesis services aimed primarily at researchers studying cell signaling transduction pathways such as PI3K-Akt, AMPK, NF-κB, TGF-β, Wnt, MAPK, and apoptosis. Its core differentiator is a catalog the company describes as the world's most complete library of phosphorylated antibodies, with 2,300+ phospho-antibodies and a proprietary AFfirm™ monoclonal antibody line validated using blocking-peptide technology; cumulative research citations exceed 46,300.
The business operates a horizontal, catalog-driven model selling to academic and government research institutions, hospitals, and pharmaceutical and biotechnology companies, with unit-based pricing (e.g., $250–$450 per antibody) and same-day delivery on stocked items. R&D is conducted through affiliates in the United States and the United Kingdom, while packaging and quality control are performed in the People's Republic of China, supporting a cost-efficient supply chain. Commercial reach is delivered via a network of 100+ authorized distributors spanning the Americas, Europe, Asia-Pacific, the Middle East, and Africa (including VWR International, Sapphire Bioscience, Kem-En-Tec Nordic, Divbio Science Europe, antibodies-online, and Funakoshi/Nacalai/AS One in Japan), supplemented by direct email ordering into regional order centers. Customer-facing services include custom phospho and polyclonal antibody development, peptide synthesis, and custom organic synthesis at milligram-to-multi-gram scale, all backed by ISO 9001 certification and a Quafidence™ six-month replacement or refund guarantee. The company has won the CiteAb "Antibody Supplier to Watch" award consecutively in 2019 and 2020 and again in 2025 for Europe, and is led by CEO Allen Wang.
