Broad incumbents

• Cytiva: Global life sciences tools and raw materials supplier (formerly GE Healthcare Life Sciences) providing bioreactor inputs, chromatography media, and bioprocessing raw materials. Overlaps with Seebio's biopharmaceutical and vaccine raw materials and separation/purification categories.
• Bio-Rad Laboratories: US-headquartered life science research and clinical diagnostics company offering a broad reagent, antibody, and IVD raw material portfolio. A global incumbent that competes across Seebio's antibody, standards, and diagnostic reagent development product lines.
• Thermo Fisher Scientific: The largest global life sciences tools company, spanning reagents, antibodies, IVD raw materials, bioprocessing inputs, and OEM services. Competes with Seebio across essentially every catalog and service category, with vastly greater scale and a global commercial footprint.
• Merck KGaA (Sigma-Aldrich): Life science division of Merck KGaA and operator of the Sigma-Aldrich brand, the most comprehensive global catalog of biochemicals, reagents, antibodies, and analytical standards. The dominant incumbent that defines pricing and quality benchmarks for Seebio's core reagent categories.

Direct peers

• ACROBiosystems: Chinese recombinant protein and reagent supplier specializing in high-quality biologics, viral proteins, and IVD raw materials. Closely comparable to Seebio's antigen, antibody, and standards catalog for diagnostic and therapeutic development customers.
• GenScript: Chinese-founded life sciences company providing gene synthesis, recombinant proteins, peptides, antibodies, and cell therapy services. Overlaps directly with Seebio's protein expression, antibody production, and custom synthesis platforms, and competes for the same IVD/biopharma customer base.
• Beijing Solarbio Science & Technology: Chinese life science reagent manufacturer with a broad catalog of biochemicals, antibodies, and cell culture products. Competes head-on with Seebio's biochemical reagent and life science research offerings, particularly for academic and biopharma customers in China.
• ABclonal Technology: Wuhan-based antibody and molecular biology reagent manufacturer offering polyclonal/monoclonal antibodies, ELISA kits, and IVD-related services. Directly overlaps Seebio's antibody production and diagnostic reagent development platforms in the Chinese life sciences market.
• Sino Biological: Beijing-headquartered recombinant protein, antibody, and reagent manufacturer serving IVD, biopharma, and research customers globally. Highly comparable to Seebio's recombinant antigen/antibody and IVD raw materials offering, with deeper scale and an established STAR Market listing.
• MedChemExpress: Global life science chemical and biochemical supplier with strong roots in the Chinese reagent ecosystem. Overlaps with Seebio's catalog biochemicals, standards, and research reagents in serving international biopharma and academic customers.
