Abstract
Fixation of a physiologically active substance on a carrier through an alkylene oxide chain allows the physioactive function of the substance to be retained to a high degree. The fixed physiologically-active substances are useful for separation and purification of materials. The carrier is preferably a thin fiber of 1.0 denier or less, and may be formed from a polymer. The alkylene oxide chain has an amino or epoxy group at one end which bonds to the carrier and a functional group at the other end which bonds to a physiologically-active substance. The carrier is preferably a thin fiber of 1.0 denier or less, and may be formed from a polymer. The alkylene oxide chain has an amino or epoxy group at one end which bonds to the carrier and a functional group at the other end which bonds to a physiologically-active substance.
