    Abstract: An embodiment of the invention relates to a device for detecting an analyte in a sample. The device comprises a fluidic network and an integrated circuitry component. The fluidic network comprises a sample zone, a cleaning zone and a detection zone. The fluidic network contains a magnetic particle and/or a signal particle. A sample containing an analyte is introduced, and the analyte interacts with the magnetic particle and/or the signal particle through affinity agents. A microcoil array or a mechanically movable permanent magnet is functionally coupled to the fluidic network, which are activatable to generate a magnetic field within a portion of the fluidic network, and move the magnetic particle from the sample zone to the detection zone. A detection element is present which detects optical or electrical signals from the signal particle, thus indicating the presence of the analyte.

  • Publication number: 20120316225
    Abstract: A modification of the existing INSM1 promoter region has been discovered that incorporated DNA elements that silence expression of neuronal genes in non-neuronal cells and that has increased the effectiveness and safety of using the INSM1 promoter for tumor treatment. One modification was addition of one or two tandem copies of neuronal restrictive silencer elements (NRSEs) derived either from the mouse nicotinic acetylcholine receptor (nAChR) or the rat superior cervical ganglion 10 (SCG10) promoters. These NRSEs were placed in the expression construct either directly upstream or downstream of the INSM1 promoter sequence. The most effective expression construct was the nAChR NRSE element positioned downstream of the INSM1 promoter. This expression construct increased the tissue specificity of the INSM1 promoter without a significant decrease in its activity. In addition, the modified INSM1 promoter was placed into a viral vector, adenovirus 5.

  • Publication number: 20120270914
    Abstract: A split luciferase-based sensor system was developed to noninvasively monitor and image phosphorylation-mediated c-Myc activation, in which the complementation of the split FL is induced by phosphorylation-mediated interaction between GSK3? and c-Myc. The complemented luciferase activity resulting from this interaction is specific to c-Myc phosphorylation and correlated with the steady-state and temporal regulation of c-Myc phosphorylation in cell culture. The sensor system also allows monitoring of c-Myc—targeted drug efficacy in intact cells and living animals. This new imaging sensor can provide insight into the role of functional c-Myc in cancer biology and is useful for the discovery and development of specific anti-c-Myc drugs.

  • Publication number: 20120149046
    Abstract: This invention relates to bioluminescent methods for detecting specific target bacteria, such as E. coli, coliforms, Enterococcus spp, Listeria spp and S. aureus in samples. The sample to be tested is incubated in a non-selective growth medium for up to 8 hours to produce a sample culture and which is then mixed with detection reagents. The detection reagents include a lysis reagent which disrupts bacterial cells in the sample, a pro-luciferin molecule which is specifically converted into luciferin by said target bacteria; and luminescence reagents which produce a luminescent signal in the presence of luciferin. The mixture of sample culture and detection reagents is then incubated and the luminescent signal from the reaction mixture measured.

  • Publication number: 20120135435
    Abstract: The present invention provides a yeast cell based system for determining factors that control the folding of amyloid proteins of diverse origins. Further the present invention provides methods of using such a system to screen for reagents that affect amyloid formation, a process that is integral to several devastating human disease including Creutzfeld-Jacob disease (CJD), fatal familial insomnia (FFI), Gertsmann-Straussler-Scheinker (GSS) syndrome, and kuru. The system of the present invention provides a rapid screening system to quickly and cheaply identify reagents that affect the folding and aggregation properties of the target protein.

  • Publication number: 20120115723
    Abstract: A composition for treating waters, e.g. ballast water or injection water for oil recovery, to kill in-situ aquatic invasive species comprises at least one biocide capable of killing both animal and plant micro-organisms. The at least one biocide preferably comprises Brilliant Green, Gentian Violet, and/or erythrosine, and a wetting agent or detergent-like compound such as CTAB or CTAC. The invention also relates to a system for treating ballast water in situ comprising means for injecting a composition for treating ballast water; means for measuring the flow rate or amount of ballast water to be treated; means for controlling the dosing of the composition; and means for storing or receiving the composition. The invention also relates to a method of detecting viable aquatic organisms in ballast water in situ comprising detecting metabolism in viable micro-organisms in ballast water and, therefore, measuring the efficacy of any treatment.

  • Publication number: 20120117667
    Abstract: An isolated polynucleotide encoding a modified luciferase polypeptide and novel coelenterazine-based substrates. The OgLuc variant polypeptide has at least 60% amino acid sequence identity to SEQ ID NO: 1 and at least one amino acid substitution at a position corresponding to an amino acid in SEQ ID NO: 1. The OgLuc variant polypeptide has at least one of enhanced luminescence, enhanced signal stability, and enhanced protein stability relative to the corresponding polypeptide of the wild-type Oplophorus luciferase.
