Özet

Preparation of poly[ethylene glycol dimethacrylate (EGDMA)-glycidyl methacrylate (GMA)] cryogel and its usability for amyloglucosidase adsorption were investigated. Cryogels were prepared by cryocopolymerization technique and then functionalized by lectin concanavalin A (Con A). The synthesized cryogel was characterized by FTIR, SEM and EDX analysis and then used for adsorption of amyloglucosidase in a continuous flow system. The maximal amyloglucosidase adsorption efficiency of Con A attached cryogel was found to be as 30.50mg/g cryogel. Con A modified cryogels were used repeatedly for 30 times without any significant decrease at the amyloglucosidase adsorption capacity. SDS-PAGE and activity studies confirmed that the desorbed amyloglucosidase was active and retained 90% of its initial activity after the adsorption/desorption processes.
