  1. 21. PCR-based detection of microorganisms in complex biological samples

    Författare :Pär-G Lantz; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Density gradient centrifugation; DNA extraction; Aqueous two-phase systems; Meat; Faeces; Cheese; Yeast; Helicobacter pylori; Yersinia enterocolitica; Listeria monocytogenes; PCR; Inhibition; Sample preparation; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The detection of microorganisms by PCR can be divided into four steps: (1) sample collection, (2) sample preparation, (3) DNA amplification and (4) detection of PCR products. The major problem in developing PCR-based detection methods is the sample preparation step. LÄS MER

  3. 22. Development of Real-Time PCR Based Methods for Detection of Viruses and Virus Antibodies

    Författare :Amal Elfaitouri; Jonas Blomberg; Helene Norder; Uppsala universitet; []
    Nyckelord :Microbiology; Real-time PCR; broadly targeted PCR; degenerated PCR; rTth DNA polymerase; thermolabile UNG; QPIA; IgM; Mikrobiologi;

    Sammanfattning : Quantitative real-time PCR (QPCR) technology has been very useful for diagnosis of viral diseases. QPCR has recently reached a level of sensitivity, simplicity, and reproducibility which allows a large number of samples to be screened rapidly, make it a suitable tool for the clinical virology diagnostics.

  4. 23. Single-molecule Detection in situ

    Författare :Chatarina Larsson; Mats Nilsson; Ulf Landegren; Sanjay Tyagi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; Molekylär medicin; Molecular Medicine; molekylär medicin genetik och patologi ;

    Sammanfattning : The human body contains a variety of different cell types that share a common genome, but differ in how they use the information encoded therein. Variation in molecular content exists even at the level of individual cells, and to provide deeper insight into complex cellular processes methods that permit analysis of each cell on its own are needed.

  5. 24. Optical Mapping of Bacterial Plasmids

    Författare :Vilhelm Müller; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; competitive binding; optical mapping; fluorescence microscopy; DNA; plasmids; CRISPR Cas9; antibiotic resistance; nanofluidics; single-molecule;

    Sammanfattning : Bacteria that have acquired resistance to antibiotics represent one of the largest threats to human health and modern health care. The genes encoding resistance are frequently spread via the transfer of plasmids, which are circular double stranded DNA molecules separate from the chromosomal DNA of the bacteria. LÄS MER

  7. 25. Molecular Tools for Biomarker Detection

    Författare :Lei Chen; Ulf Landegren; Niko Hildebrandt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rolling circle amplification; padlock probe;

    Sammanfattning : The advance of biological research promotes the emerging of new methods and solutions to answer the biological questions. This thesis describes several new molecular tools and their applications for the detection of genomic and proteomic information with extremely high sensitivity and specificity or simplify such detection procedures without compromising the performance.
