Abstract
Abstract An adsorbent for β₂-microglobulin and immunoglobulin L-chain suitable for use in an extracorporeal circulation treatment, which comprises a porous water-insoluble carrier and a compound immobilized onto said carrier, said compound satisfying that the value of log P, in which P is a partition coefficient in an octanol-water system, is not less than 2.5. The adsorbent is inexpensive, and efficiently adsorb and remove β₂-microglobulin and immunoglobulin L-chain contained in a body fluid.
