  1. 6. 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. 7. 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. 8. Genetic Analyses using Rolling Circle or PCR Amplified Padlock Probes

    Författare :Johan Banér; Sanjay Tyagi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; Padlock probes; rolling circle amplification; PCR; genotyping; microarray; expression analysis; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Medical Genetics; medicinsk genetik;

    Sammanfattning : Padlock probes are useful in a variety of genetic applications, some of which require that the probes are amplified in order to generate detectable signals. Two general padlock amplification methods, RCA and PCR, are discussed in this thesis. LÄS MER

  5. 9. Kinetics Quality Assessment for real-time PCR

    Författare :Tzachi Bar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kinetics quality assessment; PCR quality assessment; outlier detection; real-time PCR;

    Sammanfattning : For proper DNA quantification by real-time PCR, compared samples should have similar PCR efficiencies. This assumption might not be always correct, as suggested by hundreds of publications dealing with PCR inhibition. LÄS MER

  7. 10. Pre-PCR Processing Strategies for Quantitative Detection of Food-Borne Pathogens using Real-Time PCR

    Författare :Petra Wolffs; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; DNA polymerase; sample treatment; pre-PCR processing; real-time PCR; Food-borne pathogens;

    Sammanfattning : Since the development of real-time PCR, the technology has been widely applied in the field of diagnostics. In comparison with conventional PCR it has opened up the possibility of accurate quantification of microorganisms in clinical, environmental and food samples. LÄS MER
