Quantitative Fluorescent in situ hybridization (Q-FISH) is a cytogenetic technique based on the traditional FISH methodology. In Q-FISH, the technique uses labelled (Cy3 or FITC) synthetic DNA mimics called peptide nucleic acid (PNA) oligonucleotides to quantify target sequences in chromosomal DNA using fluorescent microscopy and

This unit describes a quantitative technique for measuring the lengths of telomere repeat sequences in individual chromosomes from single metaphase cells. The technique is based on fluorescence in situ hybridization (FISH) adapted for use with peptide nucleic acid (PNA) probes.

Fluorescence in situ hybridization (FISH) is the most convincing technique for locating the specific DNA sequences, diagnosis of genetic diseases, gene mapping, and identification of novel oncogenes or genetic aberrations contributing to various types of cancers.

Fluorescence in situ hybridization (FISH) has a wide spectrum of applications in current molecular cytogenetic and cancer research. This is a unique technique that can be used for chromosomal DNA analysis in all cell types, at all stages of the cell cycle, and at molecular resolution.

Quantitative FISH (Q-FISH) is a comprehensive method that allows the measuring of individual chromosome telomere length in a single cell with a resolution of 200 base pairs.

Dec 2, 2016 · Quantitative fluorescence in situ hybridization (QFISH) is an approach combining fluorescence in situ hybridization (FISH) and digital quantification of microscopic images. It has been shown to be applicable for a variety of purposes in molecular cytogenetics studies [1 – 4].

We present novel workflows for Q-FISH nanoscopy with the potential for prognostic applications and resolving novel chromatin compaction changes. DNA-fluorescence in situ hybridization (DNA-FISH) is a routine application to visualize telomeres, …

To overcome disadvantages of classical telomere length estimate, a new technique termed Q-FISH has been invented. Q-FISH provides estimate of telomere length in each individual chromosome with the resolution of 200 base pairs.

Q-FISH stands for Quantitative-Fluorescence In Situ Hybridization, a technique that uses fluorescently labeled (CCCTAA) 3 Peptide Nucleic Acid (PNA) probes to specifically hybridize to denature telomere DNA repeat arrays.

These protocols can be used on formalin-fixed paraffin-embedded tissue, lightly fixed tissue, cells isolated from tissue, cultured cells, and agar-embedded cells. The basic protocol for QFISH staining is modified to achieve excellent QFISH staining for a variety of cell preparations.
