Claim:
An endotoxin adsorbent comprising a ligand, wherein said ligand binds to the endotoxin and comprises a polylysine, wherein said endotoxin adsorbent is prepared by immobilizing an unmodified ligand polylysine onto a carrier and then reacting at least one amino group present within said polylysine, which is other than an amino group used for binding said polylysine to carrier, with an ether selected from the group consisting of butylglycidyl ether and phenylglycidyl ether, so that said ether forms an amine bond with intramolecular amino groups of said polylysine other than an amino group used for bonding said ligand to said carrier, wherein the shape of said carrier is at least one selected from the group of spherical, membranous, granular or fibrous.
