  1. 21. Electric DNA arrays for determination of pathogenic Bacillus cereus

    Författare :Yanling Liu; Sven-Olof Enfors; Helena Anderson; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacillus cereus; haemolysin; non-haemolytic enterotoxin; cytotoxin K-2; cereulide; toxin-coding genes; bacterial colony; electric DNA chip; ultrasonication; DNA fragmentation; Biochemistry; Biokemi;

    Sammanfattning : Silicon-based electric chip arrays were developed for characterization of Bacillus cereus with respect to the capacity to produce toxins involved in food poisoning and foodborne infections. Bacteria of the B. cereus group contain different sets of four toxins encoded by eight genes. LÄS MER

  3. 22. Generic Properties of Polymer Solutions

    Författare :Takashi Uematsu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photon correlation spectroscopy; collective diffusion; atomic force microscopy; relaxation; agarose gel electrophoresis; DNA; Zimm dynamics; pulsed-field gradient NMR; superdiffusion; polymer solution; blob model; gel;

    Sammanfattning : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. LÄS MER

  4. 23. Sensitivity and selectivity studies in capillary electrophoresis

    Författare :Maria Petersson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peptides; dansyl amino acids; imaging detection; cyclodextrins; enantiomer separation; acoustic levitation; solid-phase extraction; preconcentration; capillary electrophoresis; micellar electrokinetic chromatography; drugs; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Capillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.

  5. 24. Improved Techniques for High-Throughput Molecular Diagnostics

    Författare :Mario Curcio; KTH; []
    Nyckelord :DNA; Molecular Diagnostics;

    Sammanfattning : The amount of information derived from sequencing the humangenome is leading to an exponential increase in the rate atwhich genes and genetic disorders are mapped and characterized.As a consequence, the demand for genetic testing is alsodramatically increasing. LÄS MER

  7. 25. Parallel target selection by trinucleotide threading

    Författare :Pawel Zajac; Joakim Lundeberg; Afshin Ahmadian; Mats Nilsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; trinucleotide threading; multiplex amplification; expression profiling; microarray; generic tag; short tandem repeat; microsatellite; electrophoresis; single nucleotide polymorphism; allelotyping; 454; Pyrosequencing; Genetic engineering including functional genomics; Genteknik inkl. funktionsgenomik;

    Sammanfattning : DNA is the code for all life. Via intermediary RNA the information encoded by the genome is relayed to proteins executing the various functions in a cell. Together, this repertoire of inherently linked biological macromolecules determines all characteristics and features of a cell. LÄS MER
