Popis: | The enzymatically activated agaroses compared with chemically activated show 25 fold lower amount of generated aldehyde groups, 33 fold lower binding capacity for chymotrypsin, 3 fold lower proteolytic as well as amidolytic activity toward AntAlaAlaPheNA of the corresponding fixed enzyme. Trans-cinnamoylimidazole titration data demonstrate 100% active bound enzyme in the case of enzymatically oxidized agaroses and 57% for chemically oxidized. The enzymic activation offers a small number of sites for ligand attachment in a unique microenvironment. The chemical activation yields a suitable matrix for effective chymotrypsin immobilization. |
