  • Patent number: 6855510
    Abstract: Light-generating fusion proteins having a ligand binding site and a light-generating polypeptide moiety and their use as diagnostics, in drug screening and discovery, and as therapeutics, are disclosed. The light-generating fusion protein has a feature where the bioluminescence of the polypeptide moiety changes upon binding of a ligand at the ligand binding site. Tie ligand may be, for example, an enzyme present in an environment only under certain conditions, e.g., ubiquitin ligase in a hypoxic state, such that the light-generating fusion protein is “turned on” only under such conditions.

  • Patent number: 6849396
    Abstract: The present invention provides methods and apparatus for purifying metabolites of interest and conducting metabolic analyses. The methods generally involve determining metabolic flux values for a plurality of target analytes by monitoring the relative isotope abundance of a stable isotope in a substrate labeled with the stable isotope and/or one or more target metabolites formed through metabolism of the labeled substrate. Certain methods utilize multiple electrophoretic methods to separate the target analytes from other components within the sample being analyzed. The methods can be used in a variety of applications including screens to identify metabolites that are correlated with certain diseases and diagnostic screens for identifying individuals having, or susceptible to, a disease.

  • Patent number: 6846645
    Abstract: A mutiplexed enzyme assay method and substrate set for performing the method are disclosed. The method includes performing a plurality of enzyme reactions in the presence of a plurality of enzymes substrates, under conditions effective to convert an enzyme substrate to a corresponding product, where the product of each substrate and the substrate have different separation characteristics from each other and from the other substrates and their corresponding products. After performing the reactions, which may be carried out in separate or combined reactions, the substrates and products in said reactions are separated in a single separation medium. For each separated product and substrate, a separation characteristic effective to identify that product and substrate and a signal related to the amount of the product and substrate is detected. From this, one can determine the amount of substrate converted to the corresponding product in each of the reactions.

  • Patent number: 6811990
    Abstract: The present invention provides a set of methods and compositions for homogeneous coupled luminescent assays of cytotoxicity and/or proliferation of cells, as well as for enzymatic activity. In both cases the activities of the enzymes of interest are coupled to production of a high-energy molecule, which serves as a substrate for the production of light by a luciferase, typically in a single reagent mixture, with a useful readout available in 1—5 minutes. Individual cytotoxicity and proliferation signals can be measured from a single sample in 6 minutes or less. The invention also provides a 3-minute, one-step phosphatase assay. The ability to couple the activity of interest to light production in a one-step procedure gives rise to extremely rapid and flexible methods for measurement of cytotoxic effects and enzymatic activities. The assay methods are highly suitable for use in high-throughput screening procedures.

  • Patent number: 6806060
    Abstract: The present inventors have discovered that Threonine synthase is essential for fungal pathogenicity. Specifically, the inhibition of Threonine synthase gene expression in fungi results in no signs of successful infection or lesions. Thus, Threonine synthase can be used as a target for the identification of antibiotics, preferably antifungals. Accordingly, the present invention provides methods for the identification of compounds that inhibit Threonine synthase expression or activity. The methods of the invention are useful for the identification of antibiotics, preferably antifungals.

  • Patent number: 6787301
    Abstract: A method and an apparatus for laser microdissection of specimen regions (23) of interest of a specimen (4) are described. In a first step, an incomplete cut line (25) enclosing the specimen region (23) of interest is generated by means of a laser beam (7). At the incomplete point of the cut line (25), there remains a web (26) which joins the specimen region (23) of interest to the surrounding specimen (4). In a second step, the web (26) is severed with a single laser pulse directed onto it, thereby completing the cut line. The specimen region (23) of interest is in that context detached from the specimen (4) and falls by the action of gravity into a collection vessel (19).
