  • Patent number: 8609371
    Abstract: The present invention is directed to variant squalene synthase enzymes, including Saccharomyces cerevisiae squalene synthase enzymes, and to nucleic acid molecules encoding these variant enzymes. These variant enzymes produce squalene at a lower rate than the wild-type enzyme, allowing more farnesyl pyrophosphate to be utilized for production of isoprenoid compounds, while still producing sufficient squalene to allow the S. cerevisiae cells to grow without the requirement for supplementation by sterols such as ergosterol. These variant enzymes, therefore, are highly suitable for the efficient production of isoprenoids.

    Abstract: A method for obtaining a liquid from a porous solid phase is described. The method comprises forming a liquid seal at a first end of a porous solid phase to which a liquid is bound, wherein liquid of the liquid seal is immiscible with the liquid bound to the solid phase, and applying a pressure differential across the porous solid phase to cause the immiscible liquid to move through the porous solid phase towards a second end of the porous solid phase, thereby displacing the liquid bound to the porous solid phase towards the second end and releasing this liquid from the second end. Recovery of liquid from the solid phase using such methods is increased compared with corresponding methods in which no liquid seal is formed. In preferred embodiments, the liquid used to form the liquid seal is a mineral oil. The methods have particular application in nucleic acid extractions which utilise capture of nucleic acid to a solid phase. Kits and apparatus for performing the methods are also described.

  • Publication number: 20130260368
    Abstract: The invention provides chimeric capture probes immobilizable via an L-nucleic acid tail that can bind to a complementary L-nucleic acid in an immobilized probe. The capture probes are useful for capturing a target nucleic acid from a sample. The L-nucleic acid in the tail of the capture probe bind to the complementary L-nucleic acid in the immobilized probe with similar affinity as would otherwise equivalent D-nucleic acids. However, the L-nucleic acid of the capture probe tail and immobilized probes do not form stable duplexes with D-nucleic acids present in the sample containing the target nucleic acid. Binding of nucleic acids in the sample directly to immobilized probe or to the tail of the capture probe is reduced or eliminated increasing the sensitivity and/or specificity of the assay.

The materials containing a solid surface can be in the form of microparticles, fibers, beads, membranes, test tubes, pipette tips or microwells and can further comprise a magnetic core portion. The pH, salt and concentration of crowding reagent, such as polyethylene glycol or alcohol, of the solution is adjusted to levels which result in nucleic acid binding to the solid surface. The magnetic microparticles with bound polynucleotides are separated from the solution under mild alkaline conditions and the nucleic acids are eluted from the magnetic microparticles. Solutions having different nucleic acid concentrations can be normalized by restricting the availability of the solid phase surface.

  • Patent number: 8513405
    Abstract: Disclosed are a chaotropic agent; a reagent including a chaotropic agent and a lithium salt; a reagent kit including a chaotropic agent; a chaotropic agent, a reagent, a reagent kit, and a method for isolating a nucleic acid by use of a magnetic cellulose material; a method for binding a nucleic acid to a magnetic cellulose material; a method for isolating a nucleic acid; and a method for purifying a chromosome DNA. It is required that each of the chaotropic agents, the reagents, and the reagent kits works with at least one solid-phase, magnetic cellulose-containing carrier to isolate a nucleic acid from non-nucleic acid substances. In addition, each chaotropic agent includes an alcohol substance and a substrate solution for adjusting the alcohol substance to an appropriate concentration and thereby promoting binding of the nucleic acid in a sample to the magnetic cellulose.

  • Patent number: 8486659
    Abstract: The present invention is directed to variant squalene synthase enzymes, including Saccharomyces cerevisiae squalene synthase enzymes, and to nucleic acid molecules encoding these variant enzymes. These variant enzymes produce squalene at a lower rate than the wild-type enzyme, allowing more farnesyl pyrophosphate to be utilized for production of isoprenoid compounds, while still producing sufficient squalene to allow the S. cerevisiae cells to grow without the requirement for supplementation by sterols such as ergosterol. These variant enzymes, therefore, are highly suitable for the efficient production of isoprenoids.

  • Patent number: RE44693
    Abstract: Novel compositions comprised of at least one bead conjugated to a solid support and further conjugated to at least one nucleic acid and preferred methods for making the novel compositions are described. As compared to “flat” surfaces, beads linked to a solid support provide an increased surface area for immobilization of nucleic acids. Furthermore, by selecting a bead with the desired functionality, a practitioner can select a functionalization chemistry for immobilizing nucleic acids, which is different from the chemistry of the solid support.
