WebAsk an expert. Question: The diagram below shows the principle of array comparative genomic hybridization analysis. Answer the following questions. A. What information … Comparative genomic hybridization (CGH) is a molecular cytogenetic method for analysing copy number variations (CNVs) relative to ploidy level in the DNA of a test sample compared to a reference sample, without the need for culturing cells. The aim of this technique is to quickly and efficiently … See more The motivation underlying the development of CGH stemmed from the fact that the available forms of cytogenetic analysis at the time (giemsa banding and FISH) were limited in their potential resolution by the … See more Metaphase slide preparation The DNA on the slide is a reference sample, and is thus obtained from a karyotypically normal man or woman, though it is … See more Conventional Conventional CGH has been used mainly for the identification of chromosomal regions that are … See more • Cytogenetics • Virtual karyotype See more • Virtual Grand Rounds: "Differentiating Microarray Technologies and Related Clinical Implications" by Arthur Beaudet, MD • arrayMap repository: Continuously expanded … See more Array comparative genomic hybridization (also microarray-based comparative genomic hybridization, matrix CGH, array CGH, aCGH) is a molecular cytogenetic technique for the detection of chromosomal copy number changes on a genome wide and … See more A main disadvantage of conventional CGH is its inability to detect structural chromosomal aberrations without copy number changes, such as mosaicism, balanced chromosomal translocations, and inversions. CGH can also only detect gains and losses … See more

WebComparative genomic hybridization (CGH) is a technology that identifies and maps changes in DCN on a genome-wide scale. In recent years, CGH has been adapted to the … WebCGH is essentially a modified in situ hybridization. Differentially labeled test or tumor DNA (green) and reference or normal DNA (red) are cohybridized to normal metaphase spreads. Differences in the copy number between test and reference DNA are seen as differences in the ratio of green to red fluorescence intensity on the metaphase chromosomes.
