    摘要: Nucleotide and amino acid sequences of luciferase peptides that are encoded by genes within the genome of Arachnocampa (Diptera) are disclosed. Specifically provided are functional ATP-dependent luciferases that catalyze luminescence reactions with emission spectra within the blue portion of the spectrum. The present invention specifically provides isolated peptide and nucleic acid molecules, methods of identifying orthologs and active subsequences of the enzyme peptides, and methods of identifying modulators and substrates of the luciferase peptides. Methods of assays, including multiple reporter assays utilizing at least two ATP-dependent luciferases are provided.

    摘要: The present invention relates to methods and polypeptides for detecting a compound in a sample. In particular, the present invention relates to the use of a cell-free composition comprising at least one G protein coupled receptor embedded in a lipid Mayer which when expressed in a cell the N-terminus of the G protein coupled receptor, or subunits thereof, is outside the cell and the C-terminus is inside the cell, and which is capable of binding the compound. Optionally, the composition also comprises at least one accessory molecule that directly or indirectly binds an intracellular loop and/or the C-terminus of the G protein coupled receptor. The G protein coupled receptor, and/or accessory molecule when present, in combination comprise a bioluminescent protein and an acceptor molecule, which enables bioluminescent resonance energy transfer (BRET) to be used to detect the compound binding the receptor.

    摘要: The invention relates to any assay for the identification of nematicidal compounds such as anthelmintics for the control of nematodes. The assay comprises: (i) incubating a nematode sample (i.e. a “test nematode sample”) containing a pre-determined amount of nematodes with an ingestable substrate labelled with a readily detectable label, under conditions suitable for nematode feeding, wherein said incubation is conducted in the presence of said candidate nematicidal compound or follows a pre-incubation of said nematode sample with said candidate nematicidal compound, and (ii) determining whether said candidate nematicidal compound affects nematode feeding by detecting an increase or decrease in ingested substrate as compared to that which has been ingested by a control nematode sample which has been incubated without said candidate nematicidal compound.
