  • Publication number: 20150267264
    Abstract: The methods and compositions provided herein relate to the discovery of 13 STR markers, found on the human Y chromosome, having surprisingly high mutation rates when compared with 173 other Y-STR markers known today. The set of RM-Y-STRs may overcome the current dilemma of Y-chromosome analysis in forensic applications due to their extraordinary mutation properties. Embodiments of the invention include methods for allelic determination of rapidly-mutating Y-STR markers, amplification primers for the analysis of rapidly-mutating Y-STR markers, allelic ladders for analysis of rapidly-mutating Y-STR markers, and kits for the analysis of rapidly-mutating Y-STR markers.

  • Patent number: 8445657
    Abstract: The invention relates to a method for simultaneous quantification of human nuclear DNA and human male DNA in a biological sample while also detecting the presence of PCR inhibitors in a single reaction. The multiplex quantification method also provides a ratio of human nuclear and male DNA present in a biological sample. Such sample characterization is useful for achieving efficient and accurate results in downstream molecular techniques such as genotyping.

  • Publication number: 20130122505
    Abstract: The present teachings describe compositions, methods and kits for detection of one or multiple microorganism contaminants in samples. Some embodiments relate to detecting one or more microorganisms producing virulence factors such as a shiga toxin (stx) or an eae. In some embodiments, compositions, methods and kits can detect and identify individual strains and serotypes of shiga toxin producing microorganisms. Some embodiments describe compositions, methods and kits for detecting STEC microbes. Workflows for multiple microbe detection and identification are also described.

  • Publication number: 20110263437
    Abstract: The methods and compositions provided herein relate to the discovery of 13 STR are markers found on the human Y chromosome with surprisingly high mutation rates when compared with 173 other Y-STR markers known today, including those that are in common use in forensics. In addition to theoretical expectations based on elevated mutation rates, these 13 rapidly-mutating (RM) Y-STRs proved to be suitable for differentiating between closely related males, as well as between more distant male relatives and much more so than the most-commonly used Y-STRs in forensics. Our new set of RM-Y-STRs is expected to overcome the current dilemma of Y-chromosome analysis in forensic applications from current male lineage identification towards male individual identification in many cases, due to their extraordinary mutation properties as discovered here.
