    摘要: The present invention provides assay tools for the detection of biological or chemical activity in a sample. The assay tools of the invention provide direct detection using a positive signal generated on a surface of the assay tool. These assay tools provide improved methods for detection and/or identification of multiple agents (e.g., enzymes) in a sample, analysis of substrate specificity of such agents, and binding affinities and specificities of such agents. Upon activity a component is released from a first immobilised construct and then captured by a capture surface. At least two different immobilised constructs are used.

    摘要: Methods for discriminating between fully complementary hybrids and those that differ by one or more base pairs and libraries of unimolecular, double-stranded oligonucleotides on a solid support. In one embodiment, the present invention provides methods of using nuclease treatment to improve the quality of hybridization signals on high density oligonucleotide arrays. In another embodiment, the present invention provides methods of using ligation reactions to improve the quality of hybridization signals on high density oligonucleotide arrays. In yet another embodiment, the present invention provides libraries of unimolecular or intermolecular, double-stranded oligonucleotides on a solid support. These libraries are useful in pharmaceutical discovery for the screening of numerous biological samples for specific interactions between the double-stranded oligonucleotides, and peptides, proteins, drugs and RNA. In a related aspect, the present invention provides libraries of conformationally restricted probes on a solid support. The probes are restricted in their movement and flexibility using double-stranded oligonucleotides as scaffolding. The probes are also useful in various screening procedures associated with drug discovery and diagnosis. The present invention further provides methods for the preparation and screening of the above libraries.
