    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Affinity; Binding; Biomembrane; Biotin; Chromatography; Cytochalasin B; Dissociation constant; Drug absorption; Equilibrium; Glucose; GLUT1; Immobilization; Immobilized biomembrane affinity chromatography; Immobilized liposome chromatography; Interaction; Liposome; Membrane protein; Membrane vesicle; Partitioning; Phospholipid bilayer; Proteoliposome; Quantitative; Red blood cell; Solute; Specific; Streptavidin; Wheat germ agglutinin; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; Biokemi; Biochemistry;

    Sammanfattning : Specific and non-specific interactions of solutes with immobilized biomembranes were studied using chromatographic methods. Liposomes, proteoliposomes and red blood cell (RBC) membrane vesicles were immobilized by a freeze-thawing procedure, whereas whole RBCs were adsorbed in the gel beds using electrostatic interaction, binding to wheat germ agglutinin (WGA) or the streptavidin-biotin interaction.

    Sammanfattning : The human glucose transporter GLUT1 is abundant in red blood cells, the blood-brain barrier and epithelial cells, where it mediates the transport of the energy metabolite, glucose. In the present work some properties of GLUT1, including affinity binding of both substrates and inhibitors, transport rates as well as permeabilities of aromatic amino acids and drug-membrane interactions were analyzed by chromatographic methods.
