Granulocytes are advantageously collected from blood cell suspensions, especially blood or other body fluids, by bringing the blood cell suspensions into contact with a granulocyte-separating material comprising a carrier, such as a fiber, having supported thereon a fatty acid derivative containing a fatty acid moiety having 10 to 22 carbon atoms, whereby granulocytes are adsorbed on the granulocyte-separating material; and then, recovering the adsorbed granulocytes therefrom.

Granulocyte-separating material and granulocyte separator

An immune adsorbent for autoantibodies and/or immune complexes is provided which is comprised of a water-insoluble carrier and at least one low-molecular-weight substance containing a purine base or pyrimidine base as a constituent element, which is fixed to said carrier. The immune adsorbent is usually used in an adsorption apparatus comprising a vessel having fluid inlet and outlet openings and having packed therein said immune adsorbent.
