  • Patent number: 10388403
    Abstract: The invention provides a method for determining copy number variations (CNV) of a sequence of interest in a test sample that comprises a mixture of nucleic acids that are known or are suspected to differ in the amount of one or more sequence of interest. The method comprises a statistical approach that accounts for accrued variability stemming from process-related, interchromosomal and inter-sequencing variability. The method is applicable to determining CNV of any fetal aneuploidy, and CNVs known or suspected to be associated with a variety of medical conditions. CNV that can be determined according to the method include trisomies and monosomies of any one or more of chromosomes 1-22, X and Y, other chromosomal polysomies, and deletions and/or duplications of segments of any one or more of the chromosomes, which can be detected by sequencing only once the nucleic acids of a test sample.

  • Patent number: 10309927
    Abstract: Some embodiments disclosed herein provide methods of reducing reactive molecular species in a reaction carried out in a digital fluidics device having one or more electrodes by using a reaction mixture comprising an electron acceptor additive. In some embodiments, the presence of the electron acceptor additive reduces the presence of reactive molecular species in the reaction mixture. In some embodiments, the presence of the electron acceptor additive reduces the formation of gas bubbles in the digital fluidic device. Therefore, in preferred embodiments, the electron acceptor additive does not form a gas when reduced.

  • Patent number: 9736555
    Abstract: A method for cross-talk correction of intensities measured on mutually separate detection wavelength bands is presented. Each detection wavelength band relates to one of analyte-specific probe-populations contained by a sample to be analyzed. Each probe-population is capable of emitting a first signal component and a second signal component whose spectra have maxima at different wavelengths and at least the first signal component is dependent on presence of analyte detectable with that probe-population. Cross-talk corrected intensities are computed on the basis of a) the intensities measured on the detection wavelength bands, b) a value indicative of intensity occurring on an auxiliary wavelength band outside the detection wavelength bands and at least partially caused by the second signal components, and c) pre-determined cross-talk parameters.

  • Patent number: 9707555
    Abstract: Methods and devices are provided for pretreatment of a sample containing microbial cells. In some embodiments, the pretreatment of the sample is performed via the initial selective lysis, within a sample pretreatment vessel, of non-microbial cells (such as blood cells) and the subsequent centrifugal separation of the sample to remove the resulting debris and concentrate the microbial cells. An immiscible and dense cushioning liquid may be included for collecting the microbial cells adjacent to the liquid interface formed by the cushioning liquid upon centrifugation of the pretreatment vessel. After removal of a substantial quantity of the supernatant, resuspension of the collected microbial cells, and re-establishment of the cushioning liquid interface, at least a portion of the remaining suspension may be removed without substantially removing the cushioning liquid. One or more intermediate wash cycles may be performed prior to extraction of the remaining suspension, which provides a “pretreated” sample.

  • Patent number: 9606126
    Abstract: The invention provides methods to assess protein stability and to obtain sizing information. In one aspect, the screen comprises a 94 detergent panel and a series of MWCO filtered microplates. A protein of interest is bound to an affinity matrix and aliquoted into a 96-well microplate. Wells containing the immobilized protein are washed in the new detergent and then eluted in the new detergent into a collection plate. Protein not stable in the new detergent is precipitated on the resin and not present in the elutions. Half of the elution is passed through a high (i.e., 300 kDa) MWCO microplate and the other half through a low (i.e., 100 kDa) MWCO microplate. Elutions from the microplates are spotted on a nitrocellulose membrane, visualized by Western analysis (or by some other method), and quantified. The high MWCO provides stability readout and the ratio of low/high kDa provides sizing information.

  • Publication number: 20150126403
    Abstract: A method of identifying proteins present in human serum which are differentially expressed between normal individuals and patients known to have non-small cell lung cancers and asthma, as diagnosed by a physician. Human serum specimens from each population are digested with trypsin or any other suitable endoproteinase and analyzed using a liquid chromatography electrospray ionization mass spectrometer. Mass spectral data from each population is compared to determine proteins with expression intensities which are significantly differentially expressed between the normal, asthma, and lung cancer populations. Eleven proteins are found to have expression intensities which are significantly differentially expressed between the populations. Finally, the identities of the eleven proteins are obtained by comparing the mass spectral data with known databases having libraries of mass spectral data of known proteins.

  • Publication number: 20150126402
    Abstract: A method for quantifying metallothionein protein isomers is described herein. Such metallothionein isomer protein quantification is useful for detecting and monitoring disease. As illustrated herein, protein quantification is a more accurate measure of metallothionein induction than is mRNA quantification.

  • Publication number: 20150119285
    Abstract: A magnetic-assisted rapid aptamer selection (MARAS) protocol for screening DNA aptamer is proposed. The MARAS protocol is able to efficiently generate aptamers with high affinity and specificity. A rotating magnetic field or alternating magnetic field was used in combination with target-bound magnetic micro-particles or nanoparticles to select DNA aptamers having desirable affinity and specificity to the target.

  • Publication number: 20150119286
    Abstract: A high-throughput corrosion testing mechanism was developed for metals in a variety of environments in controlled, multiplexed microenvironments. Many parallel experiments can be conducted with microbial and environmental variables independently manipulated to identify the key determinants of corrosion progression. The synthetic assay design enables subsequent surface characterization of select samples within the array. In as little as one day, diverse corrosive environments can be compared quantitatively.

  • Publication number: 20150118155
    Abstract: The present invention provides a method of diagnosing the existence or risk of hyperthyroidism in a feline comprising measuring the level of expression of one or more biomarkers selected from the group consisting of e.g., IYD, TG, SLC5A5, NIS, TPO, TSHR, DUOX1, DUOX2 (ThOX), TGFB1, CSTD, DCN and SEPP1 and the expression products thereof, in a biological sample from the feline, wherein elevated expression of the one or more biomarkers in the sample relative to a control value for expression in a sample from a normal feline or feline population, or a baseline value from the feline, indicates the existence or risk of hyperthyroidism; a method of treating a feline so diagnosed; and compositions, reagents and kits for carrying out the specified methods.

  • Patent number: 9018137
    Abstract: The document pertains to a method for the purification of a ternary mixture of dimeric antibodies of the type AA, AB, BB, characterized in that for the separation of the three components and in particular for the isolation of the multi-specific fraction AB multicolumn counter current solvent gradient purification chromatography with a stationary phase load of more than 1 mg antibody mixture per milliliter stationary phase is used. It furthermore relates to a method for the identification of in particular bispecific antibody systems, which are particularly suitable for the application of such a purification method.

  • Publication number: 20150105296
    Abstract: Using NMR/MS based metabonomics and targeted lipidomics approaches the inventors have explored the metabolic phenotypes of aging and longevity in a cohort compromising centenarians, elderly and young adults. The inventors have identified biomarkers for a reduced risk of developing ageing related chronic inflammatory disorders and propose a method of diagnosing a lifestyle that allows delaying and/or avoiding ageing related chronic inflammatory disorders using hydroxy-sphingomyelin SM-OH-22:1 as biomarker.
