Autoantibody adsorbent and apparatus for removing autoantibodies using the same

摘要

An adsorbent for an autoantibody or immune complex produced by combining an autoantibody with its homologous antigen, which comprises a water-insoluble porous material and a compound having an anionic functional group immobilized onto said material, an apparatus for removing an autoantibody or immune complex thereof using the above- mentioned adsorbent and a method for removing an autoantibody or immune complex thereof from body fluid by passing body fluid through the above- mentioned removing apparatus. According to the present invention, the autoantibody or immune complex thereof can be selectively removed from body fluid without removing useful components in body fluid.
