  2. 21. Design and synthesis of -turn peptidomimetics : Applications to angiotensin II

    Author : Susanna Lindman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; peptide synthesis; turn mimetics; molecular modelling; receptor binding affinity; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

    Abstract : This study addresses the issue of how to convert peptides into drug-like non-peptides while retaining the biological activity at peptide receptors. Angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe, Ang II) was used as a model peptide. Small bioactive peptides are in most cases conformationally flexible molecules. READ MORE

  4. 22. Membrane and secretory protein production in Escherichia coli

    Author : Alexandros Karyolaimos; Jan-Willem de Gier; Matthew DeLisa; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; recombinant protein; tunable protein production; cytoplasmic membrane; periplasm; signal peptide; force profile analysis; co-translational folding; Biochemistry; biokemi;

    Abstract : Escherichia coli (E. coli) is the most widely used bacterium for the production of recombinant proteins. However, the production of proteins in its cytoplasmic membrane or periplasm is challenging. Therefore, the aim of this doctoral thesis was to develop setups for enhancing the production of membrane and secretory proteins in E. READ MORE

  5. 23. Rational and combinatorial genetic engineering approaches for improved recombinant protein production and purification

    Author : Nina Bandmann; Per-Åke Nygren; Helena Berglund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aqueous two-phase system; combinatorial library; expression vector; flow cytometry; fusion tag; partitioning; peptide library; phage display; recombinant proteins; ribosomal binding site; translation initiation; Bioengineering; Bioteknik;

    Abstract : The bacterium Escherichia coli (E. coli) is in many situations an ideal host for production of recombinant proteins, since it generally provides a rapid and economical means to achieve sufficiently high product quantities. READ MORE

  6. 24. Sample Handling Techniques in Biological and Environmental Applications Emphasizing Biomolecular Recognition and MALDI-TOF MS

    Author : Patrik Önnerfjord; Reumatologi och molekylär skelettbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein identification; microchip IMER; microdispensing; MALDI-TOF MS; fluorescence polarization; flow immunoassay; pesticide immunoassays; phenol biosensor; restricted access media; SPE; Analytical chemistry; Analytisk kemi;

    Abstract : The use of restricted access media and other stationary phases for clean-up and trace enrichment of environmental samples coupled on-line to liquid chromatography using diode array detection as well as thermospray MS is described. This on-line configuration was compared with commercially available ELISAs for the determination of triazines in complex matrices, showing superior precision and accuracy with the chromatographic method.
