    摘要: A polynucleotide is barcoded using a method whereby an isolated, individual polynucleotide is immobilized on a solid phase and stretched, targets are labeled using target-specific hybridization probes, and an individual label of an unamplified probe at each of the labeled targets is optically detected. The order of the labels is determined to form a barcode representation of the polynucleotide wherein the targets and their relative positions are represented.

    摘要: The invention provides methods and compositions for detecting binding or unbinding of a molecule to a substrate. The molecule comprises a luminophore and the substrate comprises a semiconductor which acts as a luminescence quencher to provide distance-dependent quenching of the luminophore. Binding or unbinding of the molecule, which may be covalent or noncovalent, is detected as a decrease or increase, respectively, of the detectable luminescence of the luminophore.

    摘要: The invention provides lanthanide chelates capable of intense luminescence. The celates comprise a lanthanide chelator covalently joined to a coumarin-like or quinolone-like sensitizer. Exemplary sensitzers include 2- or 4-quinolones, 2- or 4-coumarins, or derivatives thereof e.g. carbostyril 124 (7-amino-4-methyl-2-quinolone), coumarin 120 (7-amino-4-methyl-2-coumarin), coumarin 124 (7-amino-4-(trifluoromethyl)-2-coumarin), aminomethyltrimethylpsoralen, etc.The chelates form high affinity complexes with lanthanides, such as terbium or europium, through chelator groups, such as DTPA. The chelates may be coupled to a wide variety of compounds to create specific labels, probes, diagnostic and/or therapeutic reagents, etc. The chelates find particular use in resonance energy transfer between chelate-lanthanide complexes and another luminescent agent, often a fluorescent non-metal based resonance energy acceptor. The methods provide useful information about the structure, conformation, relative location and/or interactions of macromolecules.

    摘要: A method of image analysis creates super-resolution images from images with high densities of fluorophores by processing a movie in which the fluorescent molecules or particles are photobleaching or blinking. The method looks for the individual photobleaching events that can be located with high resolution (nm to tens of nanometers scale). The positions of the photobleaching or blinking events are then drawn in a composite image that is at a much higher resolution than the original fluorescence movie.
