  • Publication number: 20120157343
    Abstract: The invention provides a series of reagent compositions and methods for making and amplifying novel cDNA based probe sets from RNA samples to improve analysis with gene expression arrays. The methods globally produce probe sets with common universal linkers at one or both ends, called WRAP-Probes, wherein the linkers do not bind to the target sequences and they can efficiently bind added reporters to the probes. The universal linkers are also designed as primer binding sites for copying and amplifying the probes, either linearly with one linker, or exponentially with double linkers. The capacity to globally and exponentially amplify the probe set by PCR is a primary advantage. Adding reporters by terminal linkers also improves quantification since each probe gets equivalent signaling. The invention allows expression analysis of small research, clinical and forensic samples to enable improved diagnostics, drug discovery, therapeutic monitoring, and medical, agricultural and general research.

  • Publication number: 20120058474
    Abstract: The invention provides novel compositions and methods for detecting unlabeled nucleic acid targets using labeled polynucleotide probes and partially complementary antiprobes. The interaction of probes, antiprobes and targets result in signaling changes that indicate target frequency. This novel detection mechanism is called a DNA detection switch, and it enable end-point detection, microarray detection and real-time PCR detection of a variety of nucleic acid targets including microbial species and subspecies, drug resistant mutants, and pathogenic strains.

  • Patent number: 8122798
    Abstract: A power cutting tool includes a cutting surface, a conductive structure, and first electrode matrix comprising an array of electrical conductors. A moveable blade used to cut an object is located on the cutting surface. When at least one electrical conductor of the first electrode matrix is energized relative to the conductive structure, an electric field extends between the at least one electrical conductor and the conductive matrix to detect the presence of an object in proximity to the electric field.

  • Publication number: 20120008124
    Abstract: An imaging optical system has a plurality of mirrors, which via a beam path for imaging light, image an object field in an object plane into an image field in an image plane. The imaging optical system has an exit pupil obscuration. At least one of the mirrors has no opening for passage of the imaging light. The fourth to last mirror in the beam path is concave, resulting in an imaging optical system having improved imaging properties without compromise in throughput.
