    摘要: A separation material capable of realizing efficient separation and recovery of a blood coagulation factor, especially blood coagulation factor VIII or complex thereof with von Willebrand factor, from plasma or from samples containing blood coagulation factors.
    The separation material for separating and recovering a blood coagulation factor comprises a porous matrix having linked thereon one or more ligands each consisting of a radical exhibiting an affinity to the blood coagulation factor to be recovered, said matrix having a specific surface area of at least 1. 5 m² per milliliter of the separation material with respect to pores having diameters of at least 0.1 µ m and being derived from a porous particulate material having an exclusion limit molecular weight of at least 1.5 X 10⁶ as determined with polyethylene glycol.
    The separation material is prepared by the process steps of subjecting a porous particulate material having an exclusion limit molecular weight of at least 1.5 X 10⁶ to an activation by l,l' -carbonyldiimidazolating, tresylating, carbodiimidizing, thiopropylating, epoxidizing, bromocyanizing or formylating using corresponding activating agent and reacting the so activated porous particulate material with one or more substances which exihit after being linked as ligand on the porous particulate material an affinity to the blood coagulation factor to be recovered, so as to form a porous matrix having a specific surface area of at least 1.5 m² per milliliter of the porous particulate material with respect to pores having diameters of at least 0.1 µ m.

    摘要: Glucomannan beads which have a cross-linked structure, exhibit a degree of swelling of 1.5 to 15 ml of wet gel bed per g of dry gel, an exclusion limit molecular weight of 200 to 10⁸, and an average bead size of 1 to 500 µm.
    Such beads can be prepared by a process which comprises a process for the production of glucomannan beads having an average size of 1 to 500 µm and a cross-linked structure, which comprises suspending in an aqueous medium a solution containing 0.2 to 20% by weight of an ester of glucomannan, optionally together with a diluent, in a chlorinated hydrocarbon solvent which has a boiling point lower than that of the aqueous medium and which is immiscible or substantially immiscible with the aqueous medium; agitating the suspension, to cause the formation of droplets of the solution suspended in the aqueous medium; evaporating off the solvent contained in the liquid droplets, to leave spherical beads of the glucomannan ester; saponifying the beads of the glucomannan ester; and cross-linking the saponified beads by adding thereto a cross-linking agent in an amount of at least 0.5 part by weight per part by weight of the glucomannan beads.
