Detection of chromosome 2 and chromosome 7 within X-ray-or colchicine-induced micronuclei by fluorescence in situ hybridization

Detection of chromosome 2 and chromosome 7 within X-ray- or colchicine-induced micronuclei by fluorescence in situ hybridization.

The occurrence of chromosome 2 and chromosome 7 within micronuclei of binucleated lymphocytes induced by X-rays or colchicine was scored using the whole chromosome painting technique. The observed frequency of involvement in micronucleus formation was compared with the yield that would be expected theoretically, when the random participation of each chromosome is assumed. No difference was obse...

Development of an Alu-PCR Amplified YAC Probe Suitable for Enumeration of Chromosome 13 on Uncultured Lymphocytes and Amniocytes by Fluorescence in situ Hybridization

The main objective of the present study was to develop an efficient and reliable probe to be routinely used for detection of chromosome 13 copy numbers by interphase FISH. To achieve this, a Yeast Artificial Chromosome (YAC) containing sequences specific for human 13q12 (744D11), was cultured and the whole yeast genomic DNA was extracted. The human insert within the isolated DNA was amplified b...

Fluorescence in situ hybridization with human chromosome-specific libraries: detection of trisomy 21 and translocations of chromosome 4.

Chromosomes can be specifically stained in metaphase spreads and interphase nuclei by in situ hybridization with entire chromosome-specific DNA libraries. Unlabeled human genomic DNA is used to inhibit the hybridization of sequences in the library that bind to multiple chromosomes. The target chromosome can be made at least 20 times brighter per unit length than the others. Trisomy 21 and trans...

Detection of chromosome abnormalities in leukemia using fluorescence in situ hybridization.

Detection of chromosome aberrations in interphase nuclei using fluorescence in situ hybridization technique.

We report here several experiences of interphase cytogenetics, using fluorescence in situ hybridization (FISH) technique, for the detection of chromosome aberrations. FISH, using alpha satellite specific probes of 18, X, Y chromosomes, was done in interphase nuclei from peripheral blood of patients with Edwards' syndrome, Klinefelter's syndrome and Turner's syndrome with healthy male and female...
