  2. 16. 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

  4. 17. The kinetics of cellulose enzymatic hydrolysis : Implications of the synergism between enzymes

    Author : Priit Väljamäe; Jan-Christer Janson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Acetobacter; Cellobiohydrolase; Cellobiose; Cellulase; Cellulose; Diffusion; Endoglucanase; Hydrolysis; Inhibition; Kinetics; Model; Product; Substrate; Surface; Synergism; Trichoderma reesei; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : The hydrolysis kinetics of bacterial cellulose and its derivatives by Trichoderma reesei cellulases was studied. The cellulose surface erosion model was introduced to explain the gradual and strong retardation of the rate of enzymatic hydrolysis of cellulose. READ MORE

  5. 18. Structure and function of the presynaptically neurotoxic phospholipase A² from the Australian tiger snake - Notechis scutatus scutatus

    Author : Bengt Westerlund; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Notexin is a member of the phospholipase A2, (PLA2) family of proteins. Despitethe fact they are homologous proteins with similar sequence and almost identicalstructures, they show an impressing diversity of functions. READ MORE

  6. 19. New approaches in biomembrane chromatomatography and microchromatographic techniques

    Author : Cheng-Ming Zeng; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Development of methods for rendering chromatography more applicable to studies in lifesciences remains an area of active research. In the present work, new methods inbiomembrane chromatography and microchromatographic techniques have been developedand applied successfully to quantitative analysis of biological interactions and separations ofproteins on a micro-scale.

  7. 20. New approaches to concentration, desalting and separation of biopolymers in capillary electrophoresis

    Author : Rong Zhang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : In the first part of the thesis five new on-tube methods for concentration and desalting ofampholytes, such as peptides and proteins, are described in Papers I and II. The methods arebased on the fact that electrophoretic migration velocities decrease upon a decrease in theabsolute value of the zeta potential of a solute and the pore size of the electrophoresis mediumand upon an increase in the cross section of the electrophoresis chamber, the viscosity and theelectrical conductivity of the electrophoresis medium.
