  3. 2. Controlling DNA compaction and the interaction with model biomembranes

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

    Sammanfattning : 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. LÄS MER

  4. 3. Spectroscopic studies of dynorphin neuropeptides and the amyloid beta-peptide : The consequences of biomembrane interactions

    Författare :Loïc Hugonin; Astrid Gräslund; Bernard Lebleu; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysics; Biofysik; Biophysics; biofysik;

    Sammanfattning : Dynorphin A, dynorphin B and big dynorphin are endogenous opioid neuropeptides. They play an important role in a wide variety of physiological functions such as regulation of pain processing and memory acquisition. Such actions are generally mediated through the κ-receptors.

  5. 4. Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles

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

    Sammanfattning : 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. LÄS MER

  7. 5. Perfusion Chromatography of membrane proteins

    Författare :Margrit Roobol-Bóza; Himadri Pakrasi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : According to genomics up to 40% of all eukaryotic proteins are membrane bound. Their isolation from the biomembrane is essential for structural and functional studies. The major task in membrane protein isolation is obtaining a pure and homogeneous population, while maintaining biological activity, native conformation, and keeping cofactors bound. LÄS MER
