  2. 1. Bioanalytical separation using capillary electrophoresis : Applications with microbubbles and proteins

    Author : Leila Josefsson; Åsa Emmer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Background electrolyte; capillary electrophoresis; contrast agents; electroosmotic flow; ethylammonium nitrate; ionic liquids; microbubbles; particles; polyvinyl alcohol microbubbles; and separation; Kemi; Chemistry;

    Abstract : In this thesis the possibilities of using capillary electrophoresis as a separation technique for analysis of proteins and microbubbles is presented.A complete analytical process consists of five necessary steps of which one is the actual analysis step. For this step a suitable analytical technique is needed. READ MORE

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

    Author : Ákos Végvári; Douglas Westerlund; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Nanoparticles in capillary electrophoresis : what are the benefits?

    Author : David Malmström; Jonas Bergquist; Charlotta Turner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Abstract : Capillary electrophoresis is a technique that separate compounds based on charge and size. During the last two decades capillary electrophoresis (CE) and mass spectrometry (MS) has gained in interest, become more robust to use and able to separate neutral analytes. READ MORE

  6. 4. Method development for affinity capillary electrophoresis of ß2-glycoprotein I and biological ligands

    Author : Maria E. Bohlin; Lars G Blomberg; Niels H H Heegaard; Jan Leo Reubsaet; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Capillary Electrophoresis; β2-glycoprotein I; acidic pretreatment; pH hysteresis effect; Affinity Capillary Electrophoresis; Kemi; Chemistry;

    Abstract : The final goal of this study is to establish a microscale analysis method that allows solution phase characterization of interactions between β2-glycoprotein I (β2gpI) and some of its ligands. Human β2gpI is a phospholipid- and heparin-binding plasma glycoprotein. READ MORE

  7. 5. Sensitivity and selectivity studies in capillary electrophoresis

    Author : Maria Petersson; Centrum för analys och syntes; []
    Keywords : 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;

    Abstract : 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.
