  1. 11. Affinity Two-Phase Partitioning of Liposomes and Membranes

    Författare :Irene Barinaga-Rementeria Ramírez; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; miniaturised two-phase system; levitated drop; biotin; avidin; antibody; immunoaffinity; purification; rat lung; rat liver; caveolae; membrane; Affinity two-phase partitioning; liposome; Metabolism; Biochemistry; Biokemi; metabolism;

    Sammanfattning : Affinity two-phase partitioning based on an immunoaffinity sandwich approach for the rapid and selective purification of membranes is presented in this thesis. The method was developed by studying different parameters governing the affinity partitioning of model membranes. To this end, biotinylated liposomes were used. LÄS MER

  3. 12. Tailoring of Biomaterials using Ionic Interactions : Synthesis, Characterization and Application

    Författare :Björn Atthoff; Jöns Hilborn; Tim Bowden; Mats Andersson; Uppsala universitet; []
    Nyckelord :Chemistry; biodegradable polymers; ionomer; water uptake; protein delivery; protein adsorption; protein membrane; cell seeding efficiency; amphiphillic; inner structure; polarized membrane; Kemi;

    Sammanfattning : The interactions between polymers and components of biological systems are an important area of interest within the fields of tissue engineering, polymer chemistry, medicine and biomaterials. In order to create such a biomimetic material, it must show the inherent ability to reproduce or elicit a biological function. LÄS MER

  4. 13. Determination of benzene in urine and breath for monitoring of benzene exposure

    Författare :Göran Ljungkvist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological monitoring; benzene; breath; urine; dynamic headspace; membrane; gas chromatography; mass spectrometry; thermal desorption;

    Sammanfattning : The aim of this work was to develop and validate methods for determination of unmetabolized benzene in breath and urine. The methods were intended for the bio monitoring of benzene to assess both occupational and environmental exposure.A method was developed for the determination of benzene in end-exhaled air. LÄS MER

  5. 14. On the lateral organisation of the thylakoid membrane

    Författare :Ravi Danielsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thylakoid membrane heterogeneity; Plant biochemistry; Växtbiokemi; Thylakoid structure; Phase partition; Thylakoid fractions;

    Sammanfattning : In this work the lateral heterogeneity of the thylakoid membrane was investigated by quantifying the amount of photosystem I (PSI), photosystem II (PSII) and some PSII complexes and PSII proteins in different domains of the thylakoid. Grana, grana core, grana margins and stroma lamellae + end fractions were obtained by sonication and separation in a non-detergent, aqueous polymer two-phase system. LÄS MER

  7. 15. Dynamics of peptide chains during co-translational translocation, membrane integration & domain folding

    Författare :Rickard Hedman; Gunnar von Heijne; Daniel N. Wilson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ribosome; membrane integration; translocation; folding; arrest peptide; SecM; Biochemistry; biokemi;

    Sammanfattning : The biosynthesis of proteins occurs at the ribosomes, where amino acids are linked together into linear chains. Nascent protein chains may undergo several different processes during their synthesis. Some proteins begin to fold, while others interact with chaperones, targeting factors or processing enzymes.
