摘要: The present invention provides novel methods for identifying and monitoring epigenetic modifications, such as imprinted genes, using microarray based technology. Specifically, the invention detects imprinted genes by the presence of overlapping closed and open chromatin markers. The invention also discloses a method for detecting the loss of imprinting on a genome-wide scale, which is indicative of a variety of medical conditions. Diagnostic assays and chromatin structure markers for identifying gene imprinting and loss thereof are also disclosed.

摘要: Traditionally, in fault diagnosis systems, the user is instructed to investigate symptoms exhaustively until a single fault is identified. A more advanced known system recognises that it may be cost effective to address a fault that has been determined as being likely but not certain to exist; in preference to further examination of the symptoms. However this technique has been found not to work well when a symptom is known to be only sometimes associated with a fault. The invention addresses this problem by 1) deriving a first value, for each fault, of probable benefit of acting on that fault and for identifying the fault for which that value is greatest, 2) deriving a second value, for each symptom, of probable benefit of an investigation into that symptom and for identifying the symptom for which that second value is greatest, and 3) comparing the greatest first value with the greatest second value thereby determining when to switch from investigating symptoms to acting upon a fault. By employing the invention the aforementioned problem can be overcome because the system calculates the extent to which each symptom examination would improve the situation, assuming no further symptom investigations are used.

摘要: The present invention is an improved method of resequencing DNA using microarrays to rapidly map and identify SNPs, deletions and amplification events present in the genome of an organism. The method is performed by hybridizing a reference and a test genome to two separate arrays with each array exhibiting a specific intensity pattern. The intensity differences between the reference and the test genome arrays are used to produce a mutation map. The mapped differences are resequenced on a set of resequencing arrays to identify specific genetic mutations.

摘要: The present invention provides methods for optimizing oligonucleotide hybridization probes for use in basic and clinical research. Specifically, the invention involves hybridizing serially diluted genomic sample to the oligonucleotide probes on the array, such that a signal intensity is produced for each of the probes; computationally identifying optimized probes which exhibit signal intensities that correspond to the serial dilutions of genomic sample and are reproducibly strong relative to non-optimized probes.

摘要: During the light illumination period of a monomer addition cycle in synthesizing an DNA microarray, undesirable reflections of illumination light from various interfaces that the illumination light passes through near the synthesis surface of the substrate may reduce the light-dark contrast, and negatively affect the precision and resolution of the microarray synthesis. The present invention provides an flow cell that reduces the undesired reflections by constructing certain flow cell structures with materials that have similar refractive indexes as that of the solution that is in the oligomer synthesis chamber during the illumination period and/or constructing certain flow cell structures or covering the structures with a layer of a material that has a high extinction coefficient.

摘要: The present invention is a method for synthesizing microarrays having different oligonucleotides present within one feature area of the array. The method utilizes the techniques common to microarray synthesis, but limits the duration in which selected feature areas on the array are initially dosed with light so as to only deprotect a calculated ratio of the compounds forming the array's binding layer. The compounds initially deprotected are capped with a non-photosensitive protecting group, such as di-methoxy-trityl, to inhibit their involvement in the synthesis of a first group of DNA strands built onto the array. Once the first group of DNA strands have been synthesized, the original deprotected group may then be further processed to build one or more groups of DNA strands in the same feature area as the first group of DNA strands. The present invention also includes microarrays manufactured using the method.

摘要: The present invention is a microarray having a plurality of subarrays with a hydrophobic barrier that defines each subarray of the microarray, and a method for preparing such a microarray. The hydrophobic barrier is prepared using a microarray synthesis instrument, where NPPOC photoprotected and other hydrophobic group-bearing phosphoramidites are coupled to the microarray using light from a digital micromirror to direct formation of the hydrophobic barrier. The method utilizes hydrophobicity, a well-established property, of conventional phosphoramidite protecting groups for an entirely new application, the synthesis of hydrophobic barriers on microarrays.
