Abstract: Methods and computer software products are provided for transcriptional annotation. In one embodiment of the invention, a region of the genome where the intensity of hybridization of all the probes are above a threshold value (usually the level of non-specific hybridization) is identified. The region may be identified by aligning the probes against the genome; walking through the genome to find regions where all consecutive probes have intensities above the threshold value.

Abstract: The presently claimed invention provides methods, compositions, and apparatus for studying nucleic acids Specifically, the present invention provides a novel enrichment and labeling strategy for ribonucleic acids In one embodiment, the invention provides enriching for a population of interest in a complex population by diminishing the presence of a target sequence In a further embodiment the invention can be used to reproducibly label and detect extremely small amounts of nucleic acids

Abstract: The present invention relates to novel methods for sequencing and mapping genetic markers in polynucleotide sequences using Type-IIs restriction endonucleases. The methods herein described result in the “capturing” and determination of specific oligonucleotide sequences located adjacent to Type-IIs restriction sites. The resulting sequences are useful as effective markers for use in genetic napping, screening and manipulation.

Abstract: This invention provides nucleic acid affinity matrices that bear a large number of different nucleic acid affinity ligands allowing the simultaneous selection and removal of a large number of preselected nucleic acids from the sample Methods of producing such affinity matrices are also provided In general the methods involve the steps of a) providing a nucleic acid amplification template array comprising a surface to which are attached at least 50 oligonucleotides having different nucleic acid sequences, and wherein each different oligonucleotide is localized in a predetermined region of said surface, the density of said oligonucleotides is greater than about 60 different oligonucleotides per 1 cm2, and all of said different oligonucleotides have an identical terminal 3? nucleic acid sequence and an identical terminal 5? nucleic acid sequence b) amplifying said multiplicity of oligonucleotides to provide a pool of amplified nucleic acids, and c) attaching the pool of nucleic acids to a solid support

Abstract: This invention provides oligonucleotide based arrays and methods for speciating and phenotyping organisms, for example, using oligonucleotide sequences based on the Mycobacterium tuberculosis rpoB gene. The groups or species to which an organism belongs may be determined by comparing hybridization patterns of target nucleic acid from the organism to hybridization patterns in a database.

Abstract: In one aspect of the invention, high density arrays are used with 5? and 3? RACE (rapid amplification of cDNA ends) or RAGE (rapid amplification of Genomic DNA) in tandem to detect and characterize transcripts or genomic structures.

Abstract: In some embodiments of the invention, methods are provided to interrogate the transcriptional activity. The methods employ hybridization of a large number of oligonucleotide probes with nucleic acid derived from RNAs in a cellular compartment.

Abstract: Certain human genes have been found to be induced or repressed in host cells infected with HCMV. A large set of such genes has been identified. These have diagnostic use in determining the extent of tissue damage caused by the infection as well as in determining the stage of disease progression of the HCMV infection. Such genes are likely those involved in mediating the pathology of the infected tissues. Thus by identifying agents which are able to reverse the induction or repression of such genes, one can find candidate therapeutic agents for use in treating and or preventing HCMV-caused disease pathologies.

Abstract: This invention provides methods of monitoring the expression levels of a multiplicity of genes. The methods involve hybridizing a nucleic acid sample to a high density array of oligonucleotide probes where the high density array contains oligonucleotide probes complementary to subsequences of target nucleic acids in the nucleic acid sample.
