We describe a method for interrogating the content and primary structure of DNA by microarray analyses and to provide comprehensive genetic screening and diagnostics prior to embryo transfer within an IVF setting. We will accomplish this by the following claims: 1) an optimized embryo grading system, 2) a less invasive embryo biopsy with reduced cellular contamination, 3) an optimized DNA amplification protocol for single cells, 4) identify aneuploidy and structural chromosome abnormalities using microarrays, 5) identifying sub-telomeric chromosome rearrangements, 6) a modified DNA fingerprinting protocol, 7) determine imprinting and epigenetic changes in developing embryos, 8) performing genome-wide scans to clarify/diagnose multi-factorial genetic disease and to determine genotype/haplotype patterns that may predict future disease, 9) determining single gene disorders with or without a known DNA mutation, 10) determining mtDNA mutations and/or the combination of mtDNA and genomic (nuclear) DNA aberrations that cause genetic disease.

Methods are provided for highly sensitive and rapid in situ detection of a nucleic acid analyte of a known sequence. The method employs oligonucleotide probes in a series of optimized steps to amplify a signal and decrease background. Sensitivity is enhanced such that the method can detect as few as 1–2 copies of nucleic acid analyte per sample, the sample containing a cell, tissue or similar biological material. Methods of detecting and identifying the position of the nucleic acid analyte in a cell are also provided.

A detecting chip (2) comprising a body (5) and a frame (4) both detachable from each other. A large number of projecting pin electrodes (10) are arranged in a matrix inside the body (5). Oligonucleotide consisting of different gene sequences is fixed to the pin electrode (10). A common electrode is so disposed in a recess (8) in a frame (4) as to be out of contact with the pin electrodes (10). A DNA sample is placed in the recess (8). By applying a voltage between the common electrode and the pin electrodes (10), a current is detected to detect a hybridized two-strand DNA, thus analyzing a gene DNA.
