Abstract
A carrier for blood component adsorption includes a water-insoluble carrier composed of a fiber or particle, the water-insoluble carrier having a surface to which a functional group(s) is/are introduced, the functional group(s) containing an acidic functional group selected from the group consisting of the sulfate group, sulfite group and sulfonate group; and containing an amino group; the fiber having a fiber diameter of, or the particle having a particle diameter of, 0.5 to 20 μm.
Claims13
A water-insoluble carrier comprising a fiber, said water-insoluble carrier having a surface to which functional groups are immobilized, said functional groups containing an acidic functional group selected from the group consisting of a sulfite group and sulfonate group;
- and containing a tertiary amino group,
- said fiber having a fiber diameter of 0.5 to 20 um,
- said water-insoluble carrier having a negative charge of 1.5×10−5 to 1.5×10−3 eq/g,
- a material of said water-insoluble carrier composed of a fiber is at least one selected from the group consisting of polystyrenes, polypropylene, polypropylene-polyethylene copolymers, or poly(p-phenylene ether sulfone), and
- said acidic functional group is positioned at a terminus of said functional group and said acidic functional group is positioned at a side not bound to said water-insoluble carrier.
A column for blood component adsorption filled with a water-insoluble carrier comprising a fiber or particle, said water-insoluble carrier having a surface to which functional groups are immobilized, said functional groups containing an acidic functional group selected from the group consisting of a sulfite group and sulfonate group;
- and containing a tertiary amino group,
- said fiber having a fiber diameter of 0.5 to 20 um, and
- said water-insoluble carrier having a negative charge of 1.5×10−5 to 1.5×10−3 eq/g,
- a material of said water-insoluble carrier composed of a fiber is at least one selected from the group consisting of polystyrenes, polypropylene, polypropylene-polyethylene copolymers, or poly(p-phenylene ether sulfone), and
- said acidic functional group is positioned at a terminus of said functional group and said acidic functional group is positioned at a side not bound to said water-insoluble carrier.
