Novel application of tyramide signal amplification (TSA): ultrastructural visualization of double-labeled immunofluorescent axonal profiles.
Fluorescent immunocytochemistry (FICC) allows multiple labeling approaches when enzyme-based techniques are difficult to combine, such as in double-labeling experiments targeting small-caliber axonal segments. Nevertheless, the conversion of FICC to a product visible at the electron microscopic (EM) level requires labor-intensive procedures, thus justifying the development of more user-friendly...
متن کاملSpecific sorting of single bacterial cells with microfabricated fluorescence-activated cell sorting and tyramide signal amplification fluorescence in situ hybridization.
When attempting to probe the genetic makeup of diverse bacterial communities that elude cell culturing, researchers face two primary challenges: isolation of rare bacteria from microbial samples and removal of contaminating cell-free DNA. We report a compact, low-cost, and high-performance microfabricated fluorescence-activated cell sorting (μFACS) technology in combination with a tyramide sign...
متن کاملQuantitative assessment of picoeukaryotes in the natural environment by using taxon-specific oligonucleotide probes in association with tyramide signal amplification-fluorescence in situ hybridization and flow cytometry.
Picoeukaryotes (cells of <3 micro m in diameter) contribute significantly to marine plankton biomass and productivity, and recently molecular studies have brought to light their wide diversity. Among the methods that have been used so far to quantify aquatic microorganisms, fluorescence in situ hybridization of oligonucleotide probes combined with flow cytometry offers the advantages of both hi...
متن کاملIdentification of DNA-synthesizing bacterial cells in coastal North Sea plankton.
We describe a method for microscopic identification of DNA-synthesizing cells in bacterioplankton samples. After incubation with the halogenated thymidine analogue bromodeoxyuridine (BrdU), environmental bacteria were identified by fluorescence in situ hybridization (FISH) with horseradish peroxidase (HRP)-linked oligonucleotide probes. Tyramide signal amplification was used to preserve the FIS...
متن کاملDetection of single copy genes by two-pass tyramide signal amplification fluorescence in situ hybridization (Two-Pass TSA-FISH) with single oligonucleotide probes.
In situ detection of functional genes is informative for understanding microbial physiology. Most methods of detecting functional genes employ multiple oligonucleotides or polynucleotide probes. However, single oligonucleotide probes are superior in terms of specificity and flexibility in probe design. Here we describe the detection of a single copy functional gene, the methyl coenzyme M reduct...
