  1. 11. Partition chromatography of drugs on immobilized liposomes and biomembranes : A method applicable to screening in drug design

    Författare :Farideh Beigi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : One of the main pathways for drug passage into cells is diffusion across the lipid bilayer ofthe cell membrane. A key factor in this process is the drug partitioning into the bilayer, whichcan be translated into a retention in a chromatographic system. LÄS MER

  3. 12. Nanoporous Aluminum Oxide – A Promising Support for Modular Enzyme Reactors

    Författare :Marcus Kjellander; Gunnar Johansson; Gunnar Henriksson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoporous aluminum oxide; immobilized enzymes; bioreactor; Biokemi; Biochemistry;

    Sammanfattning : Nanoporous alumina is a rather newly characterized material that so far has found limited use in the construction of bioreactors. The material has many advantages compared to conventional immobilization matrices. I have investigated its use in flow-through bioreactors. LÄS MER

  4. 13. Selective Sorbents - Silica-immobilized affinity ligands and molecularly imprinted polymers

    Författare :Magnus Glad; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular imprinting; HPLAC; composites; TRIM; Biokemi; Biochemistry; Metabolism; affinity chromatography;

    Sammanfattning : The development of selective sorbents for the separation of various molecules, preferentially biomolecules, is described in this work. Affinity ligands were immobilized on small silica particles and used in high-performance liquid affinity chromatography (HPLAC). LÄS MER

  5. 14. Composite Materials in Molecular Imprinting Technology

    Författare :Ecevit Yilmaz; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; immobilized template; molecularly imprinted polymer; composite material; polymerization method; heterogeneous imprinting; surface; morphology; Polymer technology; Polymerteknik; biopolymers;

    Sammanfattning : Molecularly imprinted polymers (MIPs) are artificial plastic materials that mimic antibodies or enzymes. Like natural antibodies or enzymes, molecularly imprinted polymers can selectively bind target molecules or can promote catalytic reactions. LÄS MER

  7. 15. Theory of water-proton spin relaxation in complex biological systems

    Författare :Zhiwei Chang; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spin relaxation theory; immobilized macromolecules; magnetic relaxation dispersion; integral longitudinal relaxation rate; stochastic Liouville equations; multi-spin systems; cross-mode relaxation; spectral density functions;

    Sammanfattning : In complex biological systems (e.g. gels, cross-linked proteins and biological tissues), the longitudinal spin relaxation of water protons is primarily induced by exchange-mediated orientational randomization (EMOR) of intra- and intermolecular magnetic dipole-dipole couplings.
