Ya. Osinkin et al., CHEMICAL MODIFICATION OF ACETYLCHOLINESTE RASE WITH WATER-SOLUBLE CARBOXYL-CONTAINING COPOLYMERS, Vysokomolekularnye soedinenia. Seria A, 36(6), 1994, pp. 20001036-20001039
Covalent binding of acetylcholinesterase to water-soluble copolymers o
f acrylamide and acrylic acid was studied. It was found that in contra
st to radical copolymerization of the double-bond containing enzyme de
rivative, using Woodward's reagent as the condensing agent preserves t
he enzymatic activity of polymer-immobilized acetylcholinesterase.
