Human serum albumin adsorption on poly[(glycidyl methacrylate)-co-(methyl methacrylate)] beads modified with a spacer-arm-attached L-histidine ligand
(Wiley, 2006)
Poly(GMA/MMA) beads were synthesized from glycidyl methacrylate (GMA) and methyl methacrylate (MMA) in the presence of a cross-linker (i.e. ethyleneglycol dimethacrylate) (EGDMA) via suspension polymerization. The epoxy ...
Invertase reversibly immobilized onto polyethylenimine-grafted poly(GMA-MMA) beads for sucrose hydrolysis
(Elsevier Science Bv, 2006)
The epoxy group containing poly(glycidyl methacrylate-co-methyl methacrylate) poly(GMA-MMA) beads were prepared by suspension polymerisation and the beads surface were grafted with polyethylenimine (PEI). The PEI-grafted ...
Purification of lysozyme from egg white by Reactive Blue 4 and Reactive Red 120 dye-ligands immobilised composite membranes
(Elsevier Sci Ltd, 2005)
A composite membrane was synthesized from 2-hydroxyethylmethacryl ate (HEMA) and chitosan (pHEMA/chitosan) via UV initiated photo-polymerisation. Reactive Blue 4 (Blue-4) and Reactive Red 120 (Red-120) were immobilised ...
Separation and purification of lysozyme by Reactive Green 19 immobilised membrane affinity chromatography
(Elsevier Sci Ltd, 2005)
A poly(hydroxyethylmethacrylate)/chitosan (pHEMA-chitosan) composite membrane was prepared by UV-initiated photopolyrnerisation. A dye ligand (i.e. Reactive Green 19; RG 19) was immobilised onto the membrane. The water ...
Characterization of polyethylenimine grafted and Cibacron Blue F3GA immobilized poly (hydroxyethylmethacrylate-co-glycydylmethacrylate) membranes and application to bilirubin removal from human serum
(Elsevier Science Bv, 2005)
In this study, acrylic hydrogel copolymer membrane was synthesized from 2-hydroxyethylmethacrylate (HEMA) and glycidyl methacrylate (GMA) monomers. The pol ethylenimine polymer was then grafted onto membrane surface ...
Metal-chelating properties of poly(2-hydroxyethyl methacrylate-methacryloylamidohistidine) membranes
(John Wiley & Sons Inc, 2005)
Metal-chelating membranes have advantages as adsorbents in comparison with conventional beads because they are not compressible and they eliminate internal diffusion limitations. The aim of this study was to explore in ...
Adsorption of serum albumin and γ-globulin from single and binary mixture and characterization of pHEMA-based affinity membrane surface by contact angle measurements
(Elsevier Science Bv, 2005)
In this study, an affinity membrane was synthesized using 2-hydroxyethylmethacrylate (HEMA) via UV-initiated photopolymerization. A dye-ligand (i.e., Procion Red HE-3B; Red-120) was covalently immobilized onto membrane. ...
Novel hydrogel membrane based on copoly(hydroxyethyl methacrylate/p-vinylbenzylpoly(ethylene oxide)) for biomedical applications: Properties and drug release characteristics
(Wiley-V C H Verlag Gmbh, 2005)
The aim of this study was to synthesize and characterize a novel biocompatible polymeric membrane system and demonstrate its potential use in various biomedical applications. Synthetic hydrogels based on poly(hydroxyethyl ...
Removal of cadmium (II) from aqueous solumns using sporopollenin
(Parlar Scientific Publications (P S P), 2004)
Sorption of cadmium ion from aqueous solution by sporopollenin, a polymer obtained from Lycopodium clavatum, was investigated. The influences of adsorption time, temperature, pH of solution, and Cd(II) concentration on the ...
Immobilization of urease via adsorption onto L-histidine-Ni(II) complexed poly(HEMA-MAH) microspheres: Preparation and characterization
(Elsevier Sci Ltd, 2005)
Poly(2-hydroxyethyl methacrylate-co-N-methacryloly-L-histidinemethylester) poly(HEMA-MAH) microspheres was prepared via suspension polymerization. L-Histidine groups of the poly(HEMA-MAH) microspheres were then chelated ...
