Webcomparative genomic hybridisation (array CGH) 2 Microarray-based comparative genomic hybridization is a laboratory technique that is used on a DNA sample to see if any genetic material has been duplicated ... Array CGH can be performed on a blood or saliva sample from an adult or child, 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
