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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Leila Josefsson; Åsa Emmer; [2017]
    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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ákos Végvári; Douglas Westerlund; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; capillary electrophoresis; capillary electrochromatography; gel electrophoresis; agarose; polyacrylamide; b-cyclodextrin; DNA; peptide; glutathione; drug enantiomers; microchip; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi 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

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

    University dissertation from Uppsala : Institutionen för fysikalisk och analytisk kemi, Uppsala universitet

    Author : David Malmström; Jonas Bergquist; Charlotta Turner; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry; NATURVETENSKAP 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

  4. 4. Sensitivity and selectivity studies in capillary electrophoresis

    University dissertation from Technical Analytical Chemistry, Lund University

    Author : Maria Petersson; [1999]
    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.

  5. 5. Bioanalysis using capillary electrophoresis and mass spectrometry Applied on proteins, protein nanofibrils and polyvinyl alcohol microbubbles

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Leila Josefsson; Åsa Emmer; Ulrika Nilsson; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; : amyloid; capillary electrophoresis; contrast agents; detection; human blood plasma; ionic liquids; mass spectrometry; microbubbles; polyvinyl alcohol microbubbles; protein nanofibrils; proteins; Kemi; Chemistry;

    Abstract : The sequencing of the genome of various species, including the human species, have led to increased understanding about how a protein structure is generated, and how specific structures are related to the proteins’ functionality. In paper I and II of this thesis, the folding of proteins in vitro to form hierarchical nanostructures, which in vivo often have a pathological effect, have been studied. READ MORE
