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

    Författare :Peter Tiainen; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biokemisk teknik; Polymer technology; biopolymers; Polymerteknik; Biotechnology; Bioteknik; Biochemical technology; Plasmid recovery.; Composite materials; Kompositmaterial; Coating and surface treatment; Skikt och ytbehandling; Superporous agarose; Silica fibres; Plasmid purification; Anion-exchange matrices;

    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

    Författare :Jacoba G. Slagter-Jäger; Gerhart Wagner; Wolfgang Nellen; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Microbiology; antisense RNA; plasmid; U-turn; four-way junction; RNA-RNA interaction; Hfq; Mikrobiologi; Microbiology; 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

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

    Författare :Ingrid Bölin; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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. Control of Chromosome and Plasmid Replication in Escherichia coli

    Författare :Jan Olsson; Kurt Nordström; Santanu Dasgupta; Måns Ehrenberg; Anders Lobner-Olesen; Uppsala universitet; []

    Sammanfattning : Life is cellular. Cells grow and divide to give two new cells; this process is called the cell cycle. The chromosome in a bacterium is replicated into two identical copies before the cell divides. DNA replication is a fundamental process common to all forms of life. LÄS MER
