摘要:
The present invention provides novel methods and reagents for detecting the binding of protein targets to nucleic acid ligands. Using Universal Protein Stains (UPS), proteins bound by nucleic acid ligands may be labeled with a detectable moiety. The methods and reagents are particularly useful for the detection of protein targets bound to multiplexed arrays of nucleic acid ligands. The present invention also provides novel methods for the multiplexed evaluation of photocrosslinking nucleic acid ligands. The methods allow one simultaneously to: (1) evaluate the performance (dynamic range) of a plurality of photocrosslinking nucleic acid ligands; and (2) assess the specificity of each photocrosslinking nucleic acid ligand for its cognate target protein. Photocrosslinking nucleic acid ligands with the most desirable properties can then be selected for use in diagnostic and prognostic medical assays. The present invention also provides a photocrosslinking nucleic acid ligand that binds specifically to HIV gp120MN.

The present application includes biomarkers, methods, devices, reagents, systems, and kits for the detection and diagnosis of ovarian cancer. In one aspect, the application provides biomarkers that can be used alone or in various combinations to diagnose ovarian cancer or permit the differential diagnosis of a pelvic mass as benign or malignant. In another aspect, methods are provided for diagnosing ovarian cancer in an individual, where the methods include detecting, in a biological sample from an individual, at least one biomarker value corresponding to at least one biomarker selected from the group of biomarkers provided in Table 1, wherein the individual is classified as having ovarian cancer, or the likelihood of the individual having ovarian cancer is determined, based on the at least one biomarker value.

摘要:
A nucleic acid ligand “biochip” is disclosed, consisting of a solid support to which one or more specific nucleic acid ligands is attached in a spatially defined manner. Each nucleic acid ligand binds specifically and avidly to a particular target molecule contained within a test mixture, such as a bodily fluid. The target molecules include, but are not limited to, proteins (cellular, viral, bacterial, etc.) hormones, sugars, metabolic byproducts, cofactor, and intermediates, drugs, and toxins. Contacting the test mixture with the biochip leads to the binding of a target molecule to its cognate nucleic acid ligand. The biochip may then be contacted with a reagent(s) that reacts covalently with proteins and not with nucleic acids. Each protein target in the test mixture may then detected by detecting the presence of the reagent at the appropriate address on the biochip.

摘要:
The invention provides general methods for adjusting the inherent quantification range of a particular set of analytes in assays that employ capture reagents immobilized on solid supports. Specifically, the quantification range of a given analyte is adjusted to higher concentration regions by the addition of free capture reagent specific for that analyte, leaving the range of the remaining analytes the same and thereby permitting the simultaneous and accurate quantification of a plurality of analytes over a wide range of concentration values.
