  • Publication number: 20090059222
    Abstract: The present disclosure provides fully integrated microfluidic systems to perform nucleic acid analysis. These processes include sample collection, nucleic acid extraction and purification, amplification, sequencing, and separation and detection. The present disclosure also provides optical detection systems and methods for separation and detection of biological molecules. In particular, the various aspects of the invention enable the simultaneous separation and detection of a plurality of biological molecules, typically fluorescent dye-labeled nucleic acids, within one or a plurality of microfluidic chambers or channels. The nucleic acids can be labeled with at least 6 dyes, each having a unique peak emission wavelength. The present systems and methods are particularly useful for DNA fragment sizing applications such as human identification by genetic fingerprinting and DNA sequencing applications such as clinical diagnostics.

  • Publication number: 20090023603
    Abstract: A fast, multiplexed PCR system is described that can rapidly generate amplified nucleic acid products, for example, a full STR profile, from a target nucleic acid. Such systems include, for example, microfluidic biochips and a custom built thermal cycler, which are also described. The resulting STR profiles can satisfy forensic guidelines for signal strength, inter-loci peak height balance, heterozygous peak height ratio, incomplete non-template nucleotide addition, and stutter.

  • Patent number: 6537542
    Abstract: The present invention relates to a method of gene or DNA targeting in cells of vertebrate, particularly mammalian, origin. That is, it relates to a method of introducing DNA into primary or secondary cells of vertebrate origin through homologous recombination or targeting of the DNA, which is introduced into genomic DNA of the primary or secondary cells at a preselected site. The present invention further relates to primary or secondary cells, referred to as homologously recombinant (HR) primary or secondary cells, produced by the present method and to uses of the homologously recombinant primary or secondary cells. The present invention also relates to a method of turning on a gene present in primary cells, secondary cells or immortalized cells of vertebrate origin, which is normally not expressed in the cells or is not expressed at significant levels in the cells.
