  1. 1. Recombinant amelogenin - Strategies for purification and protein processing

    Författare :Johan Svensson Bonde; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Recombinant amelogenin; protein purification; fusion protein; purification tag; enamel; hydroxyapatite; matrix protein; dental regeneration; wound healing; bone formation;

    Sammanfattning : Amelogenin is an extracellular matrix protein involved in formation of enamel during early tooth development. By interacting with the forming enamel crystallites amelogenin affects their growth, so that highly elongated hydroxyapatite crystals are formed. LÄS MER

  2. 2. Recombinant subunit vaccines : protein immunogens

    Författare :Sissela Liljeqvist; KTH; []
    Nyckelord :;

    Sammanfattning : Recombinant techniques provide valuable tools for thedevelopment of modern subunit vaccines. In this thesisdifferent systems for production of recombinant subunitvaccines are presented. The strategies investigated includeprotein immunogens, live bacterial vectors and nucleicacids. LÄS MER

  3. 3. The Membrane-Spanning Domain of Complex I Investigated with Fusion Protein Techniques

    Författare :Maria Trane; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NuoN; NuoM; NuoL; covalent bound heme; Bacillus subtilis; Escherichia coli; membrane protein; His-tag; Cytochrome c; NADH:quinone oxidureductase; fusion protein;

    Sammanfattning : NADH:quinone oxidoreductase, or complex I, is a large, complex and poorly understood bioenergetic enzyme in the respiratory chain of living organisms. The enzyme has a conserved core structure, comprising fourteen protein subunits: Seven subunits protrude from the membrane and contain a flavin prosthetic group and eight iron-sulfur clusters that guide electrons from the oxidation of NADH towards the quinone binding site(s).

  4. 4. Protein engineering to explore and improve affinity ligands

    Författare :Martin Linhult; KTH; []
    Nyckelord :binding; affinity; human serum albumin HSA ; albumin-binding domain ABD ; affinity chromatography; deamidation; protein A; stabilization; Z-domain; capacity; protein G; cleaning-in-place CIP ; protein engineering; C2 receptor;

    Sammanfattning : In order to produce predictable and robust systems forprotein purification and detection, well characterized, small,folded domains descending from bacterial receptors have beenused. These bacterial receptors, staphylococcal protein A (SPA)and streptococcal protein G (SPG), possess high affinity to IgGand / or HSA. LÄS MER

  5. 5. Protein production, characterization and structure determination in structural genomics

    Författare :Esmeralda A. Woestenenk; Torleif Härd; Göran Karlsson; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Biology; protein production; protein solubility; fusion tags; nuclear magnetic resonance; structure determination; Biologi; Biology; Biologi;

    Sammanfattning : This thesis covers the process from expression of a heterologous gene in Escherichia coli to structure determination of a protein by nuclear magnetic resonance (NMR) spectroscopy. The first part concerns structural genomics-related parallel screening studies on the effect of fusion tags (in particular the His tag) on protein solubility and the use of fusion tags in fast, parallel purification protocols intended for initial biophysical characterization of human proteins produced in E.
