    摘要: Methods, compositions and articles of manufacture for assaying a sample for a target polynucleotide are provided. A sample suspected of containing the target polynucleotide is contacted with a polycationic multichromophore and a sensor polynucleotide complementary to the target polynucleotide. The sensor polynucleotide comprises a signaling chromophore to receive energy from the excited multichromophore and increase emission in the presence of the target polynucleotide. The methods can be used in multiplex form. Kits comprising reagents for performing such methods are also provided.

    摘要: The invention further relates to conjugated polymers, and methods, articles and compositions employing them as described herein. In some aspects, the invention relates to methods, articles and compositions for the detection and analysis of biomolecules in a sample. Provided assays include those determining the presence of a target biomolecule in a sample or its relative amount, or the assays may be quantitative or semi-quantitative. The methods can be performed on a substrate. The methods can be performed in an array format on a substrate, which can be a sensor. In some embodiments, detection assays are provided employing sensor biomolecules that do not comprise a fluorophore that can exchange energy with the cationic multichromophore. In some aspects biological assays are provided in which energy is transferred between one or more of the multichromophore, a label on the target biomolecule, a label on the sensor biomolecule, and/or a fluorescent dye specific for a polynucleotide, in all permutations. The multichromophore may interact at least in part electrostatically with the sensor and/or the target, and an increase in energy transfer with the polymer may occur upon binding of the sensor and the target. Other variations of the inventions are described further herein.

    摘要: This invention relates to an aggregation sensor useful for the detection and analysis of aggregants in a sample, and methods, articles and compositions relating to such a sensor. The sensor comprises first and second optically active units, where energy may be transferred from an excited state of the first optically active unit to the second optically active unit. The second optically active unit is present in a lesser amount, but its relative concentration is increased upon aggregation, increasing its absorption of energy from the first optically active units. This increase in energy transfer can be detected in variety of formats to produce an aggregation sensing system for various aggregants, including for quantitation. Other variations of the inventions are described further herein.
