What St John's Laboratory does
St John's Laboratory Ltd is a London-based private supplier of biological research reagents, founded in 2012, serving academic and biotech researchers worldwide. The company distributes through a direct e-commerce storefront (multi-currency: GBP, USD, EUR) supplemented by an international distributor network covering markets including the USA, China, Germany, Japan, Australia, India, and France.
The product portfolio is built around four pillars: primary antibodies (60,000+ polyclonal, monoclonal, recombinant, and conjugated variants), secondary antibodies (species-specific with multiple conjugations including Alexa Fluor, HRP, FITC, and Biotin), nanobodies (recombinantly developed from alpaca, validated for immunofluorescence and ELISA), and kits (10,000+ ELISA kits, CLIA kits, and antibody pairs). Supporting offerings include 1,000+ recombinant proteins (cytokines, viral antigens, cell surface proteins, labelled proteins) expressed in CHO, HEK293, and E. coli systems, plus biomolecules (blocking peptides, positive controls). Differentiated lines include 700+ KO-validated antibodies and 10,000+ trial-size antibodies that allow risk-free evaluation. Specialized verticals span COVID-19 and Hantavirus outbreak research reagents.
The business operates a product-led, transactional model: one-time purchases priced per unit (antibodies £49–£135+, ELISA kits €193–€3,582), with quote-based bulk and custom orders on multi-year contracts. Marketing is content-driven via SEO, a scientific blog, email newsletters, and earned credibility through citations in Nature, Nature Communications, EMBO Reports, and Molecular Cell. Customer segments are predominantly academic institutions (e.g., University of Heidelberg, University of Portsmouth, University of Osnabruck) and biotechnology companies, with virology researchers as a secondary segment. No revenue, headcount, funding, ownership, or M&A activity is disclosed.
