    Sammanfattning : The fullerenes, C60 and C70, can form inclusion complexes with .gamma.-cyclodextrin as the host. The complexes are formed by refluxing a water solution of . LÄS MER

  3. 2. True Monoliths as Separation Media : Homogeneous Gels for Electrophoresis and Electrochromatography in the Capillary and Microchip Modes

    Författare :Ákos Végvári; Douglas Westerlund; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; capillary electrophoresis; capillary electrochromatography; gel electrophoresis; agarose; polyacrylamide; b-cyclodextrin; DNA; peptide; glutathione; drug enantiomers; microchip; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : The thesis focuses on the development of new homogeneous gels for the separation of drug enantiomers, peptides, DNA and virus by electrophoresis and electrochromatography in capillaries and microchips. This type of separation media offers high resolution and small zone broadening. LÄS MER

  4. 3. NMR studies of the amyloid beta-peptide

    Författare :Jens Danielsson; Astrid Gräslund; Chris Dobson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR; amyloid beta peptide; structure; metal interaction; diffusion; Biophysics; Biofysik;

    Sammanfattning : The Amyloid beta peptide (Ab) is related to Alzheimer’s disease and is suggested to be the molecular pathogenic species of the disease, probably through the neurotoxic effect of Ab oligomers. Here the results from biophysical studies of Ab and fragments thereof, are presented. LÄS MER

  5. 4. Sensitivity and selectivity studies in capillary electrophoresis

    Författare :Maria Petersson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peptides; dansyl amino acids; imaging detection; cyclodextrins; enantiomer separation; acoustic levitation; solid-phase extraction; preconcentration; capillary electrophoresis; micellar electrokinetic chromatography; drugs; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Capillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.
