Abstract
An adsorbent for .beta..sub.2 -microglobulin is disclosed, which comprises a water-insoluble carrier having supported thereon, as a ligand, at least one electrolyte selected from the group consisting of a polyamino acid, a polysaccharide, a synthetic high polymer, collagen having an isoelectric point of 9.5 or more, and gelatin having an isoelectric point of 6.5 or more, wherein said electrolyte has a molecular weight not less than 1,000 and an X value of more than 2.0, wherein X is a relationship regarding the skeleton structure of said electrolyte and is the sum of A and B, wherein A represents (the number of carbon atoms of the skeleton structure)-(the number of hydrophilic groups)/(the number of hydrophilic groups); and B represents .vertline.(the number of cationic groups)-(the number of anionic groups).vertline./(the number of hydrophilic groups). The adsorbent exhibits adsorptivity for .beta..sub.2 -microglobulin at high efficiency and high selectivity.
