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 ...
Polyethylenimine-grafted and HSA-immobilized poly(GMA-MMA) aff inity adsorbents for bilirubin removal
(Wiley-Blackwell, 2005)
The epoxy-group-containing microspheres from cross-linked glycidyl methacrylate and methyl methacrylate, poly(GMA-MMA), were prepared by suspension polymerisation. The epoxy groups of the poly(GMA-MMA) microspheres were ...
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 ...
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 ...
Surface energy components of a dye-ligand immobilized pHEMA membranes: Effects of their molecular attracting forces for non-covalent interactions with IgG and HSA in aqueous media
(Elsevier, 2005)
In the present paper, we report the study of the adsorption behaviour of human immunoglobulin G (IgG), human serum albumin (HSA) and polyethylenimine (PEI) onto surfaces of Procion Green HE-4BD (PG) immobilized ...
Biosorption of Hg2+, Cd2+, and Zn2+ by Ca-alginate and immobilized wood-rotting fungus Funalia trogii
(Elsevier, 2004)
Funalia trogii biomass was immobilized in Ca-alginate gel beads. The live and beat inactivated immobilized forms were used for the biosorption of Hg2+, Cd2+ and Zn2+ ions by using plain Ca-alginate gel beads as a control ...
Polyethyleneimine-grafted poly (hydroxyethyl methacrylate-co-glycidyl methacrylate) membranes for reversible glucose oxidase immobilization
(Elsevier Science Sa, 2004)
Glucose oxidase (GOD) was immobilized onto polyethyleneimide (PEI) grafted poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) (poly(HEMA-co-GMA)) membranes. The maximum GOD immobilization capacities of the ...
Surface properties of Reactive Yellow 2 immobilised pHEMA and HEMA/chitosan membranes: characterisation of their selectivity to different proteins
(Elsevier, 2004)
Poly(hydroxyethyl methacrylate), pHEMA, and a composite pHEMA/chitosan networks were synthesized in the membrane form via UV initiated photo-polymerisation in the presence of an initiator alpha,alpha'-azoisobutyronitrile. ...
Evaluation of lysozyme adsorptive behaviour of pHEMA-based affinity membranes related to the surface energy and its components to be used in chromatographic fields
(Elsevier, 2004)
We have studied the influence of the surface energy and its components of two different dye-ligand immobilised poly(hydroxyethylmethacrylate) (pHEMA) membranes to the adsorption of a protein "lysozyme" from aqueous solutions. ...
Affinity membrane chromatography: relationship of dye-ligand type to surface polarity and their effect on lysozyme separation and purification
(Elsevier, 2004)
Two different dye-ligands, i.e. Procion Brown MX-5BR (RB-10) and Procion Green H-4G (RG-5) were immobilised onto poly(2-hydroxyethylmethacrylate) (pHEMA) membranes. The polarities of the affinity membranes were determined ...
