摘要： The present invention relates to methods, systems, and kits for detecting, quantifying and/or analyzing a fluid sample comprising molecules or particles at low concentration. In certain embodiments, the methods for detection and/or quantifying analyte molecules in a sample comprise capturing a plurality of analyte molecules on a substrate (e.g., an array comprising a plurality of reaction vessels). The substrate may then be exposed to additional reaction components such as at least one binding ligand. The substrate may additionally be exposed to a precursor labeling agent molecule, wherein the precursor labeling agent molecule, in some cases, is converted to a labeling agent molecule, which may be detected, either directly or indirectly, which determination may be related to the presence of and/or may be employed to quantify the analyte molecules. Although the various aspects of the present invention may use a number of different assay formats, in one embodiment, the assays are conducted in a plurality of reaction vessels defined, at least in part, by the distal ends of fiber optic strands.

摘要： Described herein are methods and systems for detecting DNA or RNA using single molecules array or other techniques. DNA or RNA from the sample may be fragmented and exposed to a first type of binding ligand and a second type of binding ligand that comprise nucleic acid sequences complimentary at least a portion of a sequence contained in the target DNA or RNA. At least a portion of the fragmented DNA or RNA associates with at least one of the first type of binding ligand and/or the second type of binding ligand, wherein the first type of binding ligand and second type of binding ligand comprises nucleic acid sequences complimentary to a different portions of a sequence contained in the DNA or RNA. A portion of the sample exposed to the binding ligands is analyzed to determine the number of fragmented DNA or RNA sequences.

摘要： Described herein are systems and methods for the detection of and/or determination of a measure of the concentration of analyte molecules or particles in a fluid sample. In some cases, the systems and methods employ techniques to reduce or limit the negative effects associated with non-specific binding events. Certain methods of the present invention involve associating the analyte molecules at least a first type of binding ligand and at least a second type of binding ligand, and spatially segregating the analyte molecules into a plurality of locations on a surface. The presence of an analyte molecule at or in a location may be determined by determining the presence of both the first type of binding ligand and the second type of binding ligand.
