The peroxidase-mediated deposition of hapten- and fluorochrome-labeled tyramides has recently been shown to increase the sensitivity of immunofluorescence and fluorescence in situ hybridization techniques. We have evaluated a number of red, green, and blue fluorescent tyramides for detection of antigens in tissue sections and cytospin preparations and for the detection of hapten- and horseradish peroxidase-labeled probes hybridized in situ to cells and chromosomes. With few exceptions, all fluorescent tyramide-based methods provided a considerable increase in sensitivity compared to conventional immunofluorescence and FISH methods.

A tyramide signal amplification (TSA) system was used in combination with a conventional fluorochrome-labeled 16S rRNA oligonucleotide probe to increase the sensitivity of fluorescence in situ hybridization. TSA was performed after hybridization resulted in a low fluorescence signal intensity. In contrast to the horseradish peroxidase-tyramide signal amplification (HRP-TSA) system and biotin-tyramide signal amplification (biotin-TSA) system, no additional expensive probe labeling was required.

We developed for Bacteria in environmental samples a sensitive and reliable mRNA fluorescence in situ hybridization (FISH) protocol that allows for simultaneous cell identification by rRNA FISH. Samples were carbethoxylated with diethylpyrocarbonate to inactivate intracellular RNases and pretreated with lysozyme and/or proteinase K at different concentrations. Optimizing the permeabilization of each type of sample proved to be a critical step in avoiding false-negative or false-positive results.

A one-step procedure for the synthesis of different tyramide conjugates, which can be utilized in the catalyzed reporter deposition (CARD) amplification system, is described. Succinimidyl esters of biotin, digoxigenin, and of the fluorochromes fluorescein, rhodamine, aminomethylcoumarine acetic acid, and Cy3 were coupled to tyramine in dimethylformamide (DMF) adjusted to a pH of 7.0-8.

We present a specific and sensitive method for simultaneous detection of three mRNA species in individual neurons. The method relies on the use of riboprobes labeled with [35S]-UTP, digoxigenin-UTP, or biotin-UTP. The nonradioactive probes were sequentially revealed by incubation with anti-digoxigenin immunoglobulins or streptavidin conjugated to peroxidase, followed by the use of fluorochrome-labeled tyramides as peroxidase substrates.
