Bioprocess Chromatography Resins

Life sciences tools company (Marlborough, MA; wholly-owned by Danaher Corporation since $21.4B acquisition of GE Healthcare Life Sciences in 2020) that manufactures Whatman membrane filter papers and sterile filtration products alongside its dominant chromatography resin (Capto, Sephadex, Sepharose series) and bioreactor (WAVE, XDR) platforms. Cytiva is the successor to GE Healthcare Life Sciences and Amersham Biosciences. Whatman-branded products include nitrocellulose and mixed cellulose ester membranes used in sterile filtration, diagnostics, and laboratory applications. Cytiva's role in sterile filtration is secondary to Merck KGaA and Pall — Whatman filters are more prevalent in laboratory/QC applications than primary pharmaceutical manufacturing sterilization — but Cytiva's ownership alongside Pall within Danaher creates the world's most concentrated supply position in biopharmaceutical manufacturing consumables. Danaher's combined Pall + Cytiva platform spans filtration, chromatography, bioreactors, and cell culture media — covering essentially every critical consumable step in a biologics manufacturing process.

German science company (Darmstadt; family-owned since 1668) life sciences division (MilliporeSigma in US) produces Fractogel EMD bioprocess chromatography resins alongside its Millipore filtration products and Sigma-Aldrich research chemicals. Fractogel resins (Fractogel EMD SO3-, Fractogel EMD TMAE) are an alternative to Cytiva's Capto resins for cation and anion exchange steps in biologics purification — primarily used by biomanufacturers seeking to reduce single-supplier dependence on Cytiva. Merck KGaA's same Darmstadt facility that makes sterilizing filters for pharmaceutical manufacturers (Durapore, Millipak) also produces the Fractogel resins used in the same manufacturers' upstream purification trains.

Japanese bioscience and chromatography subsidiary of Tosoh Corporation (TYO: 4042, HQ Tokyo; ~¥900B revenue); produces TOYOPEARL brand bioprocess chromatography resins — the primary alternative to Cytiva resins for protein A (Protein A resin for antibody purification), hydrophobic interaction, and ion exchange chromatography in biologics manufacturing. Tosoh Bioscience's Protein A resins (TOYOPEARL AF-rProtein A and similar) are validated alternatives to Cytiva's MabSelect series for monoclonal antibody purification — one of the few Cytiva process alternatives with sufficient regulatory documentation for biologics manufacturers to qualify. Tosoh Corporation also manufactures specialty vinyl chloride resins, chlor-alkali chemicals, and other industrial chemicals alongside its bioscience chromatography business — a Japanese conglomerate spanning plastic pipes, caustic soda, and biologics purification from one Tokyo industrial company.
