  2. 6. Quantitation, Purification and Reconstitution of the Red Blood Cell Glucose Transporter GLUT1

    Author : Shusheng Zuo; Bengt Mannervik; Bengt Persson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Cholesterol; Cytochalasin B; Glucose; GLUT1; Hummel and Dreyer analysis; Immobilization; PEG 5000 -DSPE; Biomembrane; Proteoliposome; Quantitative frontal affinity chromatography; Red blood cell streptavidin-biotin immobilization; Sulfhydryl affinity chromatography; The modified micro-Bradford CaPE assay; MALDI-ToF-MS; Biokemi; Biochemistry; Biokemi;

    Abstract : The human glucose transporter GLUT1 facilitates glucose to be accumulated on the other side of the cell membrane. The functional state of GLUT1 is uncertain due to diversity of the reports. In this thesis, the activity of red blood cell GLUT1 was extensively studied to further characterize this protein.

  5. 8. New approaches in biomembrane chromatomatography and microchromatographic techniques

    Author : Cheng-Ming Zeng; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Development of methods for rendering chromatography more applicable to studies in lifesciences remains an area of active research. In the present work, new methods inbiomembrane chromatography and microchromatographic techniques have been developedand applied successfully to quantitative analysis of biological interactions and separations ofproteins on a micro-scale.

  6. 9. Controlling DNA compaction and the interaction with model biomembranes

    Author : Marie-Louise Ainalem; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; model biomembrane; DNA compaction; cryo-TEM; null ellipsometry; dynamic light scattering; toroid; bilayer; neutron reflectivity; dendrimer; PAMAM; DNA; poly amido amine ;

    Abstract : The studies described in this thesis forms part of a larger collaborative project, Neonuclei, with the objective to design a module for packaging the negatively charged DNA into a ”neonucleus” with transcription competence. There are many applications that require control of DNA compaction, i.e. packaging or condensation. READ MORE

  7. 10. Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles

    Author : Marianna Yanez; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAMAM; Surfactant; SDS; Lipid; Bilayer; Model Biomembrane; Nucleolipid; DLPA; DLPU; DNA; RNA; Neutron Reflectometry; Poly amidoamine ; Interface; Adsorption; Polyelectrolyte;

    Abstract : The research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising materials as nanocapsules and gene vectors. READ MORE
