The present invention generally relates to spatial and structural genomic analysis compositions, which can be used for the mapping of chromosomes and structural analyses of chromosomal rearrangements, including the entire chromosome, as well as specific portions or regions of interest of the chromosomes. In some embodiments, multiple portions of the genome can be distinguished, for instance, using a first detection entity and a second detection entity different from the first detection entity. The detection entities may be immobilized relative to oligonucleotides, which may be selected to bind to different locations within the chromosome. For instance, the oligonucleotides may be at least substantially complementary to the chromosome, e.g., substantially complementary to a specific location of the chromosome.

High resolution chromosomal mapping

Comparative genomic hybridization assays and compositions for use in practicing the same are provided. A characteristic of the subject comparative genomic hybridization assays is that solid support immobilized oligonucleotide feature elements, e.g., in the form of an array, are employed. Specifically, at least first and second nucleic acid populations prepared from genomic templates are contacted with a plurality of distinct oligonucleotide feature elements immobilized on a solid support surface and the binding of the at least first and second populations is then evaluated. Also provided are kits for use in practicing the subject methods.

A computer-implemented method for viewing experimental data is provided. In certain embodiments the method comprises: a) inputting genomic array data and cytogenetic data into a computer memory; and b) producing a graphical user interface comprising: i) a chromosomal map of the genomic array data comprising a first positional indicator that indicates a position on the chromosomal map; and ii) a cytogenetic map of the cytogenetic data comprising a second positional indicator that indicates a position on the cytogenetic map.

Methods and system for viewing genomic data

The present disclosure relates to a system, composition, and method for hybridizing a microarray. The composition includes a superwetting agent. The method includes contacting the microarray with an aqueous mixture including the superwetting agent.

Composition and method for array hybridization

Comparative genomic hybridization assays and compositions for use in practicing the same are provided. In the subject methods, at least first and second genomic templates are prepared from first and second genomic sources using an amplification reaction that employs a highly processive polymerase, where the amplification reaction produces amplification products having an average molecular size of at least about 10 kb with substantially no amplification bias. The resultant templates are then employed to produce at least first and second probe nucleic acid populations. The resultant probe nucleic acid populations are then contacted with a plurality of oligonucleotide target elements immobilized on a solid support surface and the binding of at least first and second populations is then evaluated. Also provided are kits for use in practicing the subject methods.
