    Sammanfattning : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. LÄS MER

  4. 8. Electrospray Ionization Mass Spectrometry for Determination of Noncovalent Interactions in Drug Discovery

    Författare :Kurt Benkestock; Johan Roeraade; Renato Zenobi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; electrospray ionization; drug discovery; noncovalent interaction; complexes; human serum albumin HSA ; fatty acid binding protein FABP ; ribonuclease; ligand screening; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Noncovalent interactions are involved in many biological processes in which biomolecules bind specifically and reversibly to a partner. Often, proteins do not have a biological activity without the presence of a partner, a ligand. LÄS MER

  5. 9. Electrophoretic focusing in microchannels combined with mass spectrometry : Applications on amyloid beta peptides

    Författare :Saara Mikkonen; Åsa Emmer; Johan Jacksén; Tapio Kotiaho; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amyloid beta; computer simulation; electrophoresis; electrospray ionization; isoelectric focusing; isotachophoresis; MALDI; mass spectrometry; microchannel; microchip; nano-electrospray ionization; preconcentration; separation; Kemi; Chemistry;

    Sammanfattning : Analysis of low-abundance components in small samples remains a challenge within bioanalytical chemistry, and new techniques for sample pretreatments followed by sensitive and informative detection are required. In this thesis, procedures for preconcentration and separation of proteins and peptides in open microchannels fabricated on silicon microchips are presented. LÄS MER

  7. 10. On the Electrolyte Induced Aggregation of Concentrated Silica Dispersions - An Experimental Investigation Using the Electrospray Technique

    Författare :Ann-Catrin J. H. Johnsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Colloidal silica dispersion; aggregation; gelation; electrospray ES ; scanning mobility particle sizer SMPS ; synchrotron radiation small-angle x-ray scattering SR-SAXS ; electron microscopy EM ; dynamic light scattering DLS ; particle morphology; ion specificity; gel layer;

    Sammanfattning : Gels are weak, solid-like structures that arise when colloidal particles aggregate to form a network of particle clusters. A variety of colloidal systems that are important scientifically as well as in industrial applications are capable of gel formation, e.g. globular protein solutions, colloid-polymer mixtures, and metal oxides.
