Abstract
A diethylaminoethyl derivative or its salt is reacted with a synthetic resin of a macroporous type having functional groups reactive with said diethylaminoethyl derivative or its salt, having a specific area of at least 1 m.sup.2 /g-dry resin and containing macropores of which the total volume of those with pore sizes from 100 A to 2,000 A is at least 0.1 cc/g-dry resin, in the presence of an alkaline compound to give an enzyme-immobilization carrier which can provide an immobilized enzyme high in activity with good activity retentivity and also large in amount of the immobilized enzyme per unit weight of the carrier.
