دورگه سازی در محل، روشی است که در آن از پروب های اسید نوکلئیک برای بررسی انواع تغییرات ژنتیکی در سلول های دست نخورده و بافت های تثبیت شده استفاده می شود. مراحل مختلف این روش شامل انتخاب پروب، آماده سازی نمونه، تیمار پیش از دورگه سازی، دورگه سازی، شستشو، آشکارسازی و روند کنترل می باشند. انتخاب پروب مناسب یکی از جنبه های مهم انجام فرایند دورگه سازی موفقیت آمیز است. حساسیت و ویژگی in situ hybridiz...
SIRE1 is an active and relatively high copy-number retroelement belongs to the Tyl/Copia long terminal repeat (LTR) retrotransposon superfamily. Distinctive elements (ENV GAG) distributions in barley genome were observed by using fluorescent situ hybridization (FISH). We performed PCR obtain tetramethylrhodamine-dUTP (TRITC)-labelled probes. Localizations of ENV GAG domains demonstrated under c...
OBJECTIVE To develop a scoring system based on clinical findings to assist pediatricians in the diagnosis of William syndrome and to delineate when the fluorescent in-situ hybridization test to detect the microdeletion at 7q11.23 may be needed. METHODS The fluorescent in-situ hybridization test was performed on 20 patients presenting William syndrome suggestive clinical features. Eleven studi...
Manipulation of DNA fibers is very useful technique for gene analysis such as Fluorescent In Situ Hybridization (FISH). In conventional methods for manipulation of DNA fibers, FISH efficiency often decreases due to the tight adhesion between DNA fibers and substrates. In this paper, we propose a micro glass-phonorecord with concentric grooves for suspending DNA fibers with centrifugal force. As...
Although bacterioplankton and phytoplankton are generally perceived as closely linked in marine systems, specific interactions between discrete bacterioplankton and phytoplankton populations are largely unknown. However, measurements of bacterioplankton distributions during phytoplankton blooms may indicate specific microbial lineages that are responding to phytoplankton populations, and potent...
The diagnosis of malignant mesothelioma (MM) remains a clinical challenge and the fluorescence in situ hybridization (FISH) assay has been reported to be one promising tool. The present meta-analysis aimed to establish the overall diagnostic accuracy of FISH for diagnosing MM. After a systematic review of English language studies, the sensitivity, specificity and other measures of accuracy of F...
The dynamics by which homologous chromosomes pair is currently unknown. Here, we use fluorescence in situ hybridization in combination with three-dimensional optical microscopy to show that homologous pairing of the somatic chromosome arm 2L in Drosophila occurs by independent initiation of pairing at discrete loci rather than by a processive zippering of sites along the length of chromosome. B...
Microorganisms play a fundamental role in the cycling of nutrients and energy on our planet. A common strategy for many microorganisms mediating biogeochemical cycles in anoxic environments is syntrophy, frequently necessitating close spatial proximity between microbial partners. We are only now beginning to fully appreciate the diversity and pervasiveness of microbial partnerships in nature, t...
