Alcalase was scarcely immobilized on monoaminoethyl‐N‐aminoethyl (MANAE)‐agarose beads at different pH values (<20% at pH 7). The enzyme did not immobilize on MANAE‐agarose activated with glutaraldehyde at high ionic strength, suggesting a low reactivity of the enzyme with the support functionalized in this manner. However, the immobilization is relatively rapid when using low ionic strength and...
The paper shows the preparation of a new heterofunctional agarose support: amino-vinylsulfone. This has been employed to immobilize the interesting enzyme β-galactosidase from Aspergillus oryzae. The enzyme cannot be immobilized on just vinylsulfone activated support a pH values ranging from 5.0 to 9.0. Neither the enzyme was immobilized using 200mM of NaCl on amino-vinylsulfone support. However,...
