    • 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.
    • 本发明提供用于检测蛋白质靶标与核酸配体的结合的新型方法和试剂。 使用通用蛋白污渍(UPS),可以用可检测的部分标记由核酸配体结合的蛋白质。 所述方法和试剂对于检测与核酸配体复合阵列结合的蛋白质靶标特别有用。 本发明还提供了用于光交联核酸配体的多重评价的新方法。 该方法同时允许:(1)评估多个光交联核酸配体的性能(动态范围); 和(2)评估每个光交联核酸配体对其同源靶蛋白的特异性。 然后可以选择具有最理想特性的光交联核酸配体用于诊断和预后医学测定。 本发明还提供了与HIV gp120MN特异性结合的光交联核酸配体。
