Single-molecule RNA fluorescence in situ hybridization is a technique that holds great potential for the study of long noncoding RNA. It enables quantification and spatial resolution of single RNA molecules within cells via hybridization of multiple, labeled nucleic acid probes to a target RNA. It has recently become apparent that single-molecule RNA FISH probes targeting noncoding RNA are more...

The FastTag Nucleic Acid Labeling System couples haptens, fluorochromes or affinity ligands to any nucleic acid by attaching a universal, photo-or heat-activatable moiety to which any sulfhydryl-reactive compound can be linked. To demonstrate the versatility of the FastTag system, we have labeled DNA, RNA and oligonucleotide probes with a variety of maleimide-coupled moieties and have used thes...

Reading a book is also kind of better solution when you have no enough money or time to get your own adventure. This is one of the reasons we show the fluorescence in situ hybridization fish application guide as your friend in spending the time. For more representative collections, this book not only offers it's strategically book resource. It can be a good friend, really good friend with much ...

A procedure for mapping small DNA probes directly on banded human chromosomes by fluorescence in situ hybridization has been developed. This procedure allows for the simultaneous visualization of banded chromosomes and hybridization signal without overlaying two separate photographic images. This method is simple and rapid, requires only a typical fluorescence microscope, has proven successful ...

A new fluorescence in situ hybridization method using peptide nucleic acid (PNA) probes for identification of Brettanomyces is described. The test is based on fluorescein-labeled PNA probes targeting a species-specific sequence of the rRNA of Dekkera bruxellensis. The PNA probes were applied to smears of colonies, and results were interpreted by fluorescence microscopy. The results obtained fro...

In this contribution, a novel and versatile graphene oxide (GO) amplified fluorescence anisotropy (FA) strategy with improved accuracy and sensitivity for the detection of a panel of molecules, single-stranded DNA (ssDNA), adenosine and thrombin, has been successfully developed.
