  • Method for preparing immobilized enzyme conjugates and immobilized enzyme conjugates prepared thereby
    Patent number: 5541097
    Abstract: A method for preparing an immobilized enzyme conjugate, whereby the enzyme is treated with a polyfunctional amine reactive material for forming a treated enzyme-containing adduct before being immobilized on a solid support which has been contacted with a solution of a polyamine compound. The method is especially preferred for use with glucoamylase, fungal .alpha.-amylase and .beta.-amylase. Immobilized enzyme conjugates formed by use of this method include treated enzyme-containing adducts. The immobilized enzyme conjugates disclosed herein are more stable and the enzymes immobilized therein are more tightly-held than those otherwise obtained and provided.
    Type: Grant
    Filed: February 9, 1995
    Date of Patent: July 30, 1996
    Assignee: Solvay Enzymes, Inc.
    Inventors: Oreste J. Lantero, Jack W. Brewer, Sharon M. Sarber
