  1. 1. Affinity-, Partition- and Permeability Properties of the Human Red Blood Cell Membrane and Biomembrane Models, with Emphasis on the GLUT1 Glucose Transporter

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Christine Lagerquist Hägglund; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Affinity; Aromatic amino acids; Binding; Biomembrane; Biotin; Chromatography; Cytochalasin B; Dihydrocytochalasin B; Dissociation constant; Drug absorption; Ethanol; 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; Specific; Streptavidin; Tyrosine; Tryptophan; Biokemi; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi;

    Abstract : 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.

  2. 2. Chromatographic Studies of Solute Interactions with Immobilized Red Blood Cells and Biomembranes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ingo Gottschalk; Irving W. Wainer; [2002]
    Keywords : 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;

    Abstract : 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.

  3. 3. Protein engineering to explore and improve affinity ligands

    University dissertation from Stockholm : Bioteknologi

    Author : Martin Linhult; [2003]
    Keywords : binding; affinity; human serum albumin HSA ; albumin-binding domain ABD ; affinity chromatography; deamidation; protein A; stabilization; Z-domain; capacity; protein G; cleaning-in-place CIP ; protein engineering; C2 receptor;

    Abstract : In order to produce predictable and robust systems forprotein purification and detection, well characterized, small,folded domains descending from bacterial receptors have beenused. These bacterial receptors, staphylococcal protein A (SPA)and streptococcal protein G (SPG), possess high affinity to IgGand / or HSA. READ MORE

  4. 4. Fast isolation of proteins from bioreactors using affinity chromatography techniques

    University dissertation from Eva Pålsson, Tillämpad biokemi, Lunds universitet

    Author : Eva Pålsson; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chromatography; protein purification; analyses; dispersion; chromatography matrices; Biochemistry; Biokemi; Metabolism; expanded bed; metabolism; Biotechnology; Bioteknik;

    Abstract : The purification of proteins from raw materials like fermentation broth and other biological sources usually involves several purification steps and is rather time consuming and expensive. This is a major concern in the production of many important protein products e.g. pharmaceuticals such as insulin and blood coagulation factors. READ MORE

  5. 5. Insights into weak affinity antibody-antigen interactionsStudies using affinity chromatography and optical biosensor

    University dissertation from Magnus Strandh, Department of Chemistry and Biomedical Sciences, University of Kalmar, SE-391 82 Kalmar, Sweden

    Author : Magnus Strandh; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioteknik; Biotechnology; immunosensor; biosensor; weak affinity chromatography; cross-reactivity; antibody-antigen interaction; weak affinity; biomolecular recognition; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : Molecular recognition and interaction is fundamental for the function of biological systems. The properties of the interacting biomolecules dictate the type of forces involved and the strength and dynamics of the interaction. Many interactions are very strong whereas others exhibit weak affinity. READ MORE
