  1. 1. Novel Chromatography Matrices for Fast Isolation of Plasmid DNA

    Detta är en avhandling från Division of Pure and Applied Biochemistry, Lund University, Sweden

    Författare :Peter Tiainen; [2007]

    Sammanfattning : As new therapeutic areas in which genetic material is employed, i.e. gene therapy and DNA vaccination, are expanding, a substantial increase in the demand for gene vectors, e.g. LÄS MER

  3. 2. CopA and CopT: The Perfect RNA Couple

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jacoba G. Slagter-Jäger; Gerhart Wagner; Wolfgang Nellen; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; antisense RNA; plasmid; U-turn; four-way junction; RNA-RNA interaction; Hfq; Mikrobiologi; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi; mikrobiologi; Microbiology;

    Sammanfattning : Antisense RNAs regulate gene expression in many bacterial systems. The best characterized examples are from prokaryotic accessory elements such as phages, plasmids and transposons. Many of these antisense RNAs have been identified as plasmid copy number regulators where they regulate the replication frequency of the plasmid by negative feedback. LÄS MER

  4. 3. The stochastic nature of intracellular control circuits

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Johan Paulsson; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Stochastic; mesoscopic; noise; gene; plasmid; metabolic; regulation; control; Cell- och molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Chemical reactions are probabilistic by nature, causing random fluctuations inconcentrations to emerge spontaneously. In conventional (macroscopic) kinetics this internal noise is ignored under the assumption that average copy numbers are so high that fluctuations are negligible in comparison. LÄS MER

  5. 4. Temperature-inducible and calcium-regulated proteins encoded by the virulence plasmid of Yersinia

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ingrid Bölin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia; virulence plasmid; gene products; regulation; calcium; temperature; outer membrane proteins;

    Sammanfattning : The pathogenic members of the genus Yersinia, Y. pseudotuberculosis, Y. pestis and Y. enterocolitica are transmitted from animals to man and may give rise to disease with a variety of symptoms. LÄS MER

  7. 5. Integration of Aqueous Two-Phase Systems into Recovery Processes for Biomolecules

    Detta är en avhandling från Folke Tjerneld, Department of Biochemistry, Lund University

    Författare :Cecilia Kepka; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteins; proteins; plasmid DNA; large-scale; protein purification; integration; Expression; aqueous two-phase systems; enzymology; Proteiner; enzymologi;

    Sammanfattning : The main scope of this thesis has been to study and develop new purification methods and also to further develop existing methods for purification to enhance their efficacy. Important parameters in the development of the methods are that they should be suitable for scale-up and possible to be integrated into recovery processes. LÄS MER
