What Antibodies.com does

Antibodies.com is a Cambridge, UK-based private supplier of protein research tools founded in 2015, operating through three wholly-owned legal entities in the United Kingdom, the United States (St. Louis, MO), and Sweden (Stockholm). The company sells a catalog of more than 100,000 products — primary and secondary antibodies, recombinant proteins and peptides, ELISA kits (including a 4,000+ SKU 90-minute format), isotype controls, trial-size antibodies, assay kits, and biosimilar antibodies — to academic researchers, pharmaceutical and biotechnology companies, and contract research organizations across more than 100 countries.

The company's core technology is a multi-level product validation stack: CRISPR/Cas9 knockout validation for specificity, HuProt genome-wide protein array testing against 19,000+ human proteins with an S-score specificity threshold of 2.5, SEC-HPLC purity assessment, SPR binding kinetics for nanodisc-embedded transmembrane proteins, and functional/in vivo assays (FACS, ELISA, ADCC, tumor suppression) for biosimilars. ISO 9001:2015 certification underpins the quality system. The catalog is partially sourced through a licensing program that commercializes reagents developed at academic and private research institutes.

The business model is direct-to-researcher e-commerce with one-time per-unit pricing ($375–$420 per antibody, $40 freight) supplemented by an international distributor network and regional hubs in St. Louis and Stockholm. Customer acquisition is content-driven: nine PhD-level authors produce application guides and educational articles, while travel grants (up to $500 quarterly), citation rewards ($50 per publication), product review rewards ($100–$175), and a 20% new-lab discount drive community engagement. There is no subscription or enterprise licensing revenue model disclosed.
