Detection of chromosome aberrations in the human interphase nucleus by visualization of specific target DNAs with radioactive and non-radioactive in situ hybridization techniques: diagnosis of trisomy 18 with probe L1.84 [PDF]

open access: yes, 1986
The localization of chromosome 18 in human interphase nuclei is demonstrated by use of radioactive and nonradioactive in situ hybridization techniques with a DNA clone designated L1.84.

Fluorescent in situ hybridization (FISH) on the veterinary diagnostic field

open access: yesActa Fytotechnica et Zootechnica, 2016
Proceeding deals with of genomic changes detectable by FISH . The DSD syndrom in Yorkshire terrier 78,XY t (Y-;6p+) was observed by the use of X and Y FISH WCP probes. Following results indicated numerous genomic changes in cancers. Using comparative

Protocol for the use of signal amplification by exchange reaction-fluorescence in situ hybridization on adult formalin-fixed paraffin-embedded mouse lung tissue

open access: yesSTAR Protocols, 2023
Summary: Fluorescence in situ hybridization (FISH) is a useful tool for analyzing RNA expression, but difficulties arise with low-abundance RNA and in tissues that are formalin-fixed paraffin-embedded (FFPE) because reagents can be expensive.

Distribution of the Primary Endosymbiont (Candidatus Uzinura Diaspidicola) Within Host Insects from the Scale Insect Family Diaspididae

open access: yesInsects, 2012
It has long been known that armored scale insects harbor endosymbiotic bacteria inside specialized cells called bacteriocytes. Originally, these endosymbionts were thought to be fungal symbionts but they are now known to be bacterial and have been named ...

Suboptimal concordance in testing and retesting results of triple-negative breast carcinoma cases among laboratories: one institution experience

open access: yesCancer Cell International, 2019
Background Triple-negative breast carcinoma (TNBC) patients do not benefit from hormone- or human epidermal growth factor receptor 2- (HER2-) targeted therapies. Accurate testing is pivotal for these patients. Methods TNBC cases that were retested at our

Differential Analysis of Active and Inactive Genes in Human Neutrophils by Chromosomal In Situ Hybridization [PDF]

open access: yes, 2003
In situ hybridization has been widely used for localization of specific genes in interphase cell nuclei. The sites of signals, however, do not represent the activity of the gene transcription in the nuclei.

Morphological detection of X- and Y-chromosomes in smears and paraffin-embedded tissues using a non-isotopic in situ hybridization technique (NISH) [PDF]

open access: yes, 1994
Pharyngeal smears and paraffin-embedded tissue specimens (skeletal muscle, kidney) obtained from 10 male and 10 female individuals were evaluated using non-isotopic in situ hybridization (NISH) with commercial X- and Y-specific biotinylated probes which ...

A Novel Amplification Method of Nonradioactive In Situ Hybridization Signal for Specific RNA with Biotinylated Tyramine [PDF]

open access: yes, 1997
For a better performance of nonradioactive in situ hybridization for specific RNA sequences, signal amplification is sometimes required especially in the use of clinical specimens processed under suboptimal conditions and in the analysis of gene ...

In Situ Gene Expression in Native Cryofixed Bone Tissue

open access: yesBiomedicines, 2022
Bone is a very complex tissue that is constantly changing throughout the lifespan. The precise mechanism of bone regeneration remains poorly understood.

Fluorescence in situ hybridization to chromosomes as a tool to understand human and primate genome evolution [PDF]

open access: yes, 2005
For the last 15 years molecular cytogenetic techniques have been extensively used to study primate evolution. Molecular probes were helpful to distinguish mammalian chromosomes and chromosome segments on the basis of their DNA content rather than solely ...
