A highly useful tool for studying lncRNAs is simultaneous RNA-DNA FISH, which reveals the localization and quantitative information of RNA and DNA in cellular contexts. However, a simple combination of RNA FISH and DNA FISH often generates disappointing results because the fragile RNA signals are often damaged by the harsh conditions used in DNA FISH for denaturing the DNA. Here, we describe a robust and simple RNA-DNA FISH protocol, in which amino-labeled nucleic acid probes are used for. RNA Fluorescence In Situ Hybridization (RNA-FISH) › RNA FISH with ViewRNA Assays › The RNAscope® Multiplex Assay uses a novel and proprietary method of in situ hybridization (ISH) to visualize single RNA molecules per cell in fresh frozen or embedded tissue samples This approach, called single-molecule RNA fluorescence in situ hybridization (smRNA FISH), allows subcellular localization and absolute quantification of RNA molecules in individual cells. Here, we describe a simple smRNA FISH protocol for two-color imaging of a circular RNA, CDR1as, simultaneously with an unrelated messenger RNA. The protocol can be adapted to circRNAs that coexist with overlapping, noncircular mRNA isoforms produced from the same genetic locus We developed an RNA-FISH assay for detection of the FGFR3-TACC3 fusion in FFPE samples of human BC tissues.

But DNA FISH has also played a crucial role in a different field — genome organization. Indeed, DNA FISH has been instrumental to confirm the hypothesis originally proposed in 1885 by Car Rabl that, in interphase nuclei, chromosomes form discrete masses now known as chromosomal territories 1. Since then, dozens of research groups have harnessed DNA FISH to study various aspects of chromosome. Abstract. Die genetische Information eines Organismus wird in Form von Nukleinsäuren gespeichert. Diese Nukleinsäuren - DNA (deoxyribonucleic acid, Desoxyribonukleinsäure) und RNA (ribonucleic acid, Ribonukleinsäure) - sind lange lineare Polymere.Das bedeutet, sie bestehen aus Nukleotidbausteinen, die wiederum je aus einem Zucker, einem Phosphatrest und einer von vier Basen aufgebaut sind

Chromosome conformation capture (3C)-based techniques have revolutionized the field of nuclear organization, partly replacing DNA FISH as the method of choice for studying three-dimensional chromosome architecture. Although DNA FISH is commonly used for confirming 3C-based findings, the two techniques are conceptually and technically different and comparing their results is not trivial FISH is useful, for example, to help a researcher or clinician identify where a particular gene falls within an individual's chromosomes. The first step is to prepare short sequences of single-stranded DNA that match a portion of the gene the researcher is looking for. These are called probes. The next step is to label these probes by attaching one of a number of colors of fluorescent dye.DNA.

FISH often used for finding specific features in DNA for use in genetic counselling, medicine, and species identification. FISH can also be used to detect and localize specific RNA target (mRNA, IncRNA, miRNA) in cells. Diseases that are diagnosed using FISH include Angelman syndrome, 22q13 deletion syndrome acute lymphoblastic leukemia, Cri-du-chat, and Down syndrome. FISH can also be used. Stellaris RNA FISH can distinguish different RNA variants from one or multiple genes allowing for additional insight into correlated gene expression at the single cell level. The amplification and overexpression of genes in cell lines and tissue can be robustly assessed with this technology, allowing the Stellaris method to serve as a proxy for immunofluorescence and DNA FISH.

FISH of whole cells always consists of four parts: Fixation of the sample containing the target cells. Fixation stabilizes macromolecules and cytoskeletal structures thus preventing lysis of the cells during hybridization. At the same time fixation permeabilize the cell walls for the fluorescently-labeled oligonucleotide probe molecules Principles of fluorescence in situ hybridization (a) The basic elements of FISH are a DNA probe and a target sequence. (B) Before hybridization the DNA probe is labelled indirectly with a hapten (left panel) or directly labelled via the incorporation of a fluorophore (right panel). (c) The labeled probe and the target DNA are denatured. (d) Combining the denatured probe and target allows the annealing of complementary DNA sequences.
