  • Publication number: 20150337298
    Abstract: In certain embodiments, the present invention provides a way of “digitally” marking different the alleles of different chromosomes by using a transposase to insert differently barcoded transposons into genomic DNA before further analysis. According to this method, each allele becomes marked with a unique pattern of transposon barcodes. Because each unique pattern of transposon barcodes identifies a particular allele, the method facilitates determinations of ploidy and copy number variation, improves the ability to discriminate among homozygotes, heterozygotes, and patterns arising from sequencing errors, and allows loci separated by uninformative stretches of DNA to be identified as linked loci, thereby facilitating haplotype determinations. Also provided is a novel artificial transposon end that includes a barcode sequence in two or more positions that are not essential for transposition.

  • Publication number: 20140134624
    Abstract: The present teachings provide methods, compositions, and kits for detecting the presence of protein aggregates. In some embodiments, the protein aggregate is treated with a labeled precursor, and the labeled precursor is incorporated into the protein aggregate to form a labeled protein aggregate. The labeled protein aggregate is then measured, thus detecting the presence of the protein aggregate. In some embodiments, the labeled protein aggregate is detected by interaction of labeled precursors, for example by a proximity ligation assay.

  • Patent number: 8555562
    Abstract: A window well cover jack is disclosed. The window well cover jack has three arms: a base arm, a support arm and an actuator handle, all connected to aid in the lifting of a window well cover and to allow egress. In one embodiment, the jack is lockable in a stowed position. It is also possible to add a spring assist to aid in the lifting of a window well cover. Ideally, the window well cover jack is also lockable in a deployed position to aid in holding an ajar window well cover so as to facilitate escape. A simple link, which is easily broken by emergency crews with the proper tools but secure against intruders without said tools, connects the window well cover jack to a window well cover.
