Concanavalin a immobilized affinity adsorbents for reversible use in yeast invertase adsorption
Yavuz, H; Akgol, S; Arica, Y; Denizli, A (Wiley-V C H Verlag Gmbh, 2004)Concanavalin A (Con A) immobilized poly(2-hydroxyethyl methacrylate) (PHEMA) beads were investigated for specific adsorption of yeast invertase from aqueous solutions. PHEMA beads were prepared by a suspension polymerization ... -
Covalent immobilisation of invertase onto a reactive film composed of 2-hydroxyethyl methacrylate and glycidyl methacrylate: properties and application in a continuous flow system
Bayramoglu, G; Akgol, S; Bulut, A; Denizli, A; Arica, MY (Elsevier Science Sa, 2003)Invertase was covalently immobilised on the poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) (poly(HEMA-GMA)) film. The invertase immobilisation capacity of the films was increased as the GMA ratio increased in the ... -
Dye-affinity hollow-fibres and their lysozyme adsorption-desorption characteristics
Senel, S; Akgol, S; Arica, Y; Denizli, A (John Wiley & Sons Ltd, 2001)Dye-affinity adsorption is increasingly used for protein separation. Hollow-fibres have advantages as adsorbents in comparison to conventional bead supports because they are not compressible and can eliminate internal ... -
Fluoride release from microporous poly(2-hydroxyethyl methacrylate) membranes
Yildirmaz, G; Akgol, S; Arica, MY; Sonmez, H; Denizli, A (Elsevier Science Bv, 2003)Fluoride ion is commonly used in the preventive treatment of tooth decay and when provided with extra fluoride, children living in regions that lack fluoride benefit from it. In the present study, the clinical properties ... -
Hydrolysis of sucrose by invertase immobilized onto novel magnetic polyvinylalcohol microspheres
Akgol, S; Kacar, Y; Denizli, A; Arica, MY (Elsevier Sci Ltd, 2001)The magnetic polyvinylalcohol (PVAL) microspheres were prepared by crosslinking glutaraldehyde. 1,1 ' -Carbonyldiimidazole (CDI), a carbonylating agent was used for the activation of hydroxyl groups of polyvinylalcohol, ... -
Poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) reactive membrane utilised for cholesterol oxidase immobilisation
Akgol, S; Bayramoglu, G; Kacar, Y; Denizli, A; Arica, MY (John Wiley & Sons Ltd, 2002)Poly(2-hydroxyethyl methacrylate-co-glycidyl methacrylate) p(HEMA-GMA) membrane was prepared by UV-initiated photopolymerisation of 2-hydroxyethyl methacrylate (HEMA) and glycidyl methacrylate (GMA) in the presence of an ... -
Polyhydroxyethylmethacrylate/polyhydroxybutyrate composite membranes for fluoride release
Yildirmaz, G; Akgol, S; Arica, MY; Sonmez, H; Denizli, A (Wiley, 2003)Controlled release technology is a recent technology which has considerable potential in the fields of medicine, pharmacy, and agriculture. Fluoride ion is commonly used in the preventive treatment of decay, and when ... -
Reversible immobilization of urease onto Procion Brown MX-5BR-Ni(II) attached polyamide hollow-fibre membranes
Akgol, S; Yalcinkaya, Y; Bayramoglu, G; Denizli, A; Arica, MY (Elsevier Sci Ltd, 2002)Urease was immobilized onto Procion Brown MX-5BR attached and Ni(II) incorporated microporous polyarnide hollow-fibre membrane via adsorption. Urease immobilization onto the polyamide hollow-fibre membrane from aqueous ...
