  2. 21. Biophysical studies of membrane interacting peptides derived from viral and Prion proteins

    Author : Kamila Oglęcka; Astrid Gräslund; Stephen White; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Prion peptides; Doppel peptide; Influenza fusion peptides; peptide-membrane interactions; translocation; linear dichroism; circular dichroism; Biophysics; Biofysik; Biophysics; biofysik;

    Abstract : This thesis focuses on peptides derived from the Prion, Doppel and Influenza haemagglutinin proteins in the context of bilayer interactions with model membranes and live cells. The studies involve spectroscopic techniques like fluorescence, fluorescence correlation spectroscopy (FCS), circular and linear dichroism (CD and LD), confocal fluorescence microscopy and NMR.

  4. 22. Structural and functional studies of biomolecules with NMR and CD spectroscopy

    Author : Evangelos Papadopoulos; Astrid Gräslund; Göran Karlsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; protein structure; nouse Doppel; HTH; C-repressor; potassium channel; Biophysics; Biofysik; Biophysics; biofysik;

    Abstract : Experimentally derived biomolecular structures were determined by Nuclear Magnetic Resonance (NMR). The properties of selected peptides and proteins in solution and in membrane mimicking micelles were observed by circular Dichroism (CD), mass spectrometry (MS), and other spectroscopic techniques.
