What Rachael West does

Selleck Chemicals is a privately held supplier of biochemical research reagents, founded in 2009 and operating globally with 51-100 employees. The company catalogs and distributes small-molecule inhibitors, primary and biosimilar antibodies, recombinant proteins, screening compound libraries, and bioreagents organized across 50+ signaling pathways (including PI3K/Akt/mTOR, MAPK, JAK/STAT, epigenetics, apoptosis, autophagy, and cell cycle) and disease areas such as ovarian, breast, lung, and colorectal cancer, Alzheimer's disease, diabetes, and immunology.

Its core technology consists of a deeply indexed product catalog spanning inhibitors (including PROTACs and antibody-drug conjugates), antibodies, proteins, and compound libraries, supported by a global e-commerce platform with 16+ localized regional websites. Scientific credibility is reinforced by product citations in Nature, Science, and Cell publications, with 17 Nobel Prize winners having published 60 papers using Selleck products. The company has no disclosed AI, software platform, or proprietary computational capabilities; its competitive position rests on catalog breadth, scientific endorsement, and distribution reach.

Selleck generates revenue through direct online sales of research-use-only biochemicals to academic institutions, pharmaceutical companies, and biotech firms worldwide. Pricing is quote-based rather than publicly listed, products are sold for research use only (not clinical or human use), and go-to-market relies on the global website network as the primary marketing, catalog, and ordering channel. Customer segments include academic research institutions, pharma/biotech drug-discovery teams, and use-case verticals in oncology, immunology, and neuroscience, with a fragmented long-tail of institutional buyers across North America, Europe, and Asia Pacific.

Direct peers

• MedChemExpress (MCE): MCE is the closest direct competitor, specializing in small-molecule inhibitors, compound libraries, and research reagents across the same signaling pathways (PI3K/Akt/mTOR, MAPK, etc.) and serving academic and pharma researchers worldwide.
• Abcam: Abcam supplies research-grade antibodies and related reagents globally, with comparable antibody catalog breadth and a direct-to-researcher e-commerce model similar to Selleck's distribution approach.
• Cell Signaling Technology (CST): CST is a leading provider of antibodies and reagents for signaling pathway research, overlapping significantly with Selleck's antibody and pathway-focused reagent portfolio for academic and pharma researchers.
• Tocris Bioscience (Bio-Techne): Tocris supplies high-purity research chemicals, inhibitors, antibodies, and peptides for life science research, with similar signaling-pathway catalog depth and academic/pharma customer base as Selleck.
• Cayman Chemical: Cayman manufactures and distributes research biochemicals including enzyme inhibitors, antibodies, and assay kits, with substantial overlap with Selleck's product range and customer segments.
• APExBIO: APExBIO sells small-molecule inhibitors, APIs, compound libraries, and reagents for life science research directly to academic and industrial researchers, competing head-to-head with Selleck on catalog breadth and pricing.
• Santa Cruz Biotechnology: Santa Cruz Biotechnology offers antibodies, biochemicals, and research reagents for academic and industrial life science research, overlapping with Selleck's antibody and small-molecule inhibitor offerings.

Broad incumbents

• Thermo Fisher Scientific: Thermo Fisher is a diversified life sciences giant offering research reagents, antibodies, and analytical tools through brands like Invitrogen and Pierce; competes with Selleck as part of a much broader portfolio serving similar customers.
• Avantor: Avantor distributes laboratory products, chemicals, and bioprocessing materials to life sciences customers, serving some of the same academic and pharma customers as Selleck but as a much broader distributor rather than a focused reagent manufacturer.
• Sigma-Aldrich (Merck KGaA): Sigma-Aldrich, part of Merck's Life Science division, is the largest incumbent supplier of research chemicals, antibodies, and biochemicals globally; it competes broadly with Selleck across nearly every product category but with vastly broader portfolio scale.
