Abstract
A carrier for immobilization of physiologically active substances is prepared by treating an assembly of regenerated cellulose fibers having a single fiber fineness of from 0.5 to 30 deniers and a length of at least 1 millimeter with a solution of a polymer having an acid anhydride group. This carrier is easy to handle and permits immobilization of a large amount of a physiologically active substance. Thus it can be used as a catalyst for chemical reactions, a specific absorbent for separation and purification, a material for clinical examination, or a medical material.
