Abstract Background: To produce a reliable probe suitable for aneuploidy detection of chromosome 13 on uncultured lymphocytes and amniocytes by fluorescence in situ hybridization (FISH), we used a contig of three overlapping cosmids mapped to 13q12.3. Methods: The cosmid DNA carrying the expected sequences of human chromosome 13 was isolated from host cells and labelled with biotin-11-dUTP. Th...
Fluorescence in situ hybridization (FISH) requires nucleic acid probes, including deoxyribonucleic acid (DNA), ribonucleic acid (RNA), or nucleic acid analogs, labeled directly with fluorophores, or capable of indirect association with fluorophores. The nucleic acid provides the FISH assay with its specificity through complementary pairing of the probe nucleotides with nucleotides of the target...
Background & Objective: Soft tissue sarcomas (STS) constitute an uncommon and heterogeneous group of tumors of mesenchymal origin and various cytogenetic abnormalities ranging from distinct genomic rearrangements, such as chromosomal translocations and amplifications, to more intricate rearrangements involving multiple chromosomes. Fluorescence in situ...
Fluorescence in situ hybridization (FISH) is a molecular biology technique that enables the localization, quantification, and identification of microorganisms sample. This has found applications several areas, most notably environmental, for quantification diversity assessment and, clinical, rapid diagnostics infectious agents. The FISH method based on fluorescently labeled nucleic acid probe w...

Objective The Subtelomeric rearrangements are increasingly being investigated in cases of idiopathic intellectual disabilities (ID) and congenital abnormalities (CA) but have also been suspected to be responsible for unexplained recurrent miscarriage (RM). We have noticed a higher risk of subtelomeric translocations in association with CA and ID. Such rearrangements can go unnoticed through con...
In the current study, the sensitivity and specificity of methods of HER2 status detection were studied in 55 patients presenting with gastric/gastroesophageal junction carcinoma (30 intestinal and 25 diffuse), in small biopsy (endoscopy; n=33) and resection specimens (n=22). The primary objective of the present study was to compare various methods for the assessment of HER2 status, with regards...
