  • Patent number: 9851330
    Abstract: A nucleic acid (NA) detection method combines ultra-specific probe, on-chip isotachophoresis (ITP) which can separate single strand and double strand NAs, and enzyme amplification. The ITP device has a sieving matrix between the LE (leading electrolyte) and TE (trailing electrolyte) reservoirs, for separating double-strand and single-strand NAs. The LE or TE reservoir also contains a spacer ion having a mobility between the LE and the TE. The sample and a double-strand NA probe is added to the TE reservoir, the probe being formed of a protector strand modified with a fluorescent molecule and a complement strand, where the protector strand is released in the presence of the target NA. Fluorescent signal is detected downstream of the sieving matrix. Alternatively, the protector strand is modified with an enzyme and a single-strand NA modified with a substrate of the enzyme is added to the reaction mixture downstream of the sieving matrix.

  • Patent number: 9598737
    Abstract: Disclosed is an enhanced method for rapid and cost-effective analysis of sequences of a microorganism by semi-conductor sequencing, preferably ion-torrent sequencing. This method provides for full length analysis and of multiple areas (e.g. genes) of multiple genomes. These methods identify genetic mutations of a particular gene that are responsible for conferring resistance or sensitivity to an antibiotic or other chemical compound. Multiple different species, strains and/or serotypes of a particular organism are rapidly and efficiently screened and mutations identified along with the complete genome of an organism. By selecting primers pairs of similar size and GC content that produce amplicons with sequences spanning the entire genome, a single PCR reaction analyzed by ion torrent methodology can determine the sequence of a complete genome. Methods are useful to sequences the genomes of viral agents, such as influenza virus, and bacterial agents, such as tuberculosis bacteria.

  • Patent number: 9017956
    Abstract: Provided herein are uses of genes for HOG, Ras and cAMP signal transduction pathways to treat fungal infection. To regulate the HOG pathway of Cryptococcus neoformans, roles of SSK1, TCO2, SSK2, PBS2, HOG1, ENA1 and NHA1 genes were investigated to find that a biosynthesis level of ergosterol is increased when these genes are inhibited. When the genes are inhibited, a large amount of ergosterol is distributed on a fungal cell membrane. Accordingly, since there are many working points of an ergosterol-binding antifungal agent, an efficiency of the ergosterol-binding antifungal agent can be considerably improved. To regulate the Ras and cAMP pathways of Cryptococcus neoformans, roles of RAS1, RAS2, CDC24, GPA1, CAC1, ACA1, PKA1, HSP12 and HSP122 genes were investigated to find that a sensitivity to a polyene- or azole-based drug is increased when these genes are inhibited.

  • Publication number: 20150104795
    Abstract: A method of increasing biogenic production of a combustible gas from a subterranean geologic formation is described. The method may include extracting formation water from the geologic formation, where the extracted formation water includes at least a first species and a second species of microorganism. The method may also include analyzing the extracted formation water to identify the first species of microorganism that promotes the biogenic production of the combustible gas. An amendment may be introduced to the formation water to promote the growth of the first species of microorganism, and the biological characteristics of the formation water may be altered to decrease a population of the second species in the geologic formation.

  • Patent number: 8999649
    Abstract: The present invention provides a molecular construct capable of fluorescent resonance energy transfer (FRET), comprising a linker peptide, and donor and acceptor fluorophore moieties, where the linker peptide is a substrate of a botulinum neurotoxin selected from the group consisting of synaptobrevin, syntaxin and SNAP-25, or a fragment thereof capable being cleaved by the botulinum neurotoxin, and separates the donor and acceptor fluorophores by a distance of not more than 10 nm, and where emission spectrum of the donor fluorophore moiety overlaps with the excitation spectrum of the acceptor fluorophore moiety; or where the emission spectra of the fluorophores are detectably different. Also provided are isolated nucleic acid expressing the construct, kits comprising said construct and cell lines comprising said nucleic acid. Further provided are methods of detecting a BoNT using the above described construct via FRET, and methods for detecting a BoNT using surface plasmon resonance imaging.

  • Patent number: 9000137
    Abstract: The present invention provides nucleic acid aptamers that bind to Plasmodium proteins lactate dehydrogenase and histidine-rich protein II, and uses thereof for the diagnosis of malaria. Aptamers against histidine-rich protein II may be used to detect the presence of Plasmodium species in general, whereas aptamers against lactate dehydrogenase can be used to specifically detect Plasmodium falciparum.

  • Publication number: 20150056624
    Abstract: The method for isolating nucleic acids from a food sample comprising the following steps: a) obtaining a food enrichment culture; b) transferring a portion of the food enrichment culture into a reaction vessel thereby providing a food enrichment sample and providing a water-immiscible phase in contact with the food enrichment culture; c) lysing the food enrichment sample to provide a lysed sample; d) isolating nucleic acids from the lysed sample. Food enrichment culture samples are known to contain high concentrations of organic and/or liposoluble inhibitors. By contacting the enrichment culture sample with a water-immiscible phase before the actual DNA extraction procedure starts, part of the lipophilic inhibitors is expected to cross the phase interface due to an enhanced solubility in the organic phase and thereby become depleted.
