Comparative Genomic Hybridization

Comparative Genomic Hybridization (CGH)

Spectral Karyotyping and Comparative Genomic Hybridization Data

Spectral Karyotyping (SKY) (1–7) and Comparative Genomic Hybidization (CGH) (8– 11) are complementary fluorescent molecular cytogenetic techniques that have revolutionized the detection of chromosomal abnormalities. SKY permits the simultaneous visualization of all human or mouse chromosomes in a different color, facilitating the detection of chromosomal translocations and rearrangements (Figur...

Array comparative genomic hybridization in male infertility.

BACKGROUND Male infertility caused by a maturation arrest of spermatogenesis is a condition with an abrupt stop in spermatogenesis, mostly at the level of primary spermatocytes. The etiology remains largely unknown. METHODS We focused on patients with a complete arrest at the spermatocyte level (n = 9) and used array comparative genomic hybridization to screen for deletions or duplications th...

Leptospire genomic diversity revealed by microarray-based comparative genomic hybridization.

Comparative genomic hybridization was used to compare genetic diversity of five strains of Leptospira (Leptospira interrogans serovars Bratislava, Canicola, and Hebdomadis and Leptospira kirschneri serovars Cynopteri and Grippotyphosa). The array was designed based on two available sequenced Leptospira reference genomes, those of L. interrogans serovar Copenhageni and L. interrogans serovar Lai...

Genomic imbalances in childhood medulloblastoma by comparative genomic hybridization

We used comparative genomic hybridization (CGH) technique to identify the genetic changes in 12 childhood medulloblastoma samples obtained from archived paraffinembedded tissues belonging to children (0.7-15 years-old) using double step degenerate oligonucleotide-primed polymerase chain reaction (DOP-PCR). CGH analysis showed that the most common genetic alterations were gains of chromosomes 4p...
