  • SOLID-PHASE CARRIER, PRODUCTION METHOD FOR SOLID-PHASE CARRIER, CARRIER FOR AFFINITY REFINING, PRODUCTION METHOD FOR FILLER FOR AFFINITY CHROMATOGRAPHY, FILLER FOR AFFINITY CHROMATOGRAPHY, CHROMATOGRAPHY COLUMN, AND REFINING METHOD
    Publication number: 20170043320
    Abstract: There are provided a solid-phase carrier and a carrier for affinity refining that exhibit high dynamic binding capacity when a ligand is immobilized, have excellent antifouling properties, and are unlikely to have non-specific adsorption of impurities. The solid-phase carrier has a functional group capable of fixing a ligand and is characterized by having a group having a sulfinyl group, a sulfide group, an oxy group or an imino group, and a hydroxyl group, a thiol group, an amino group, a carboxy group, a sulfate group, a phosphate group or an alkanoyl group.
