Improved localization of fluorescent tyramides for fluorescence in situ hybridization using dextran sulfate and polyvinyl alcohol


, : Improved localization of fluorescent tyramides for fluorescence in situ hybridization using dextran sulfate and polyvinyl alcohol. Journal Of Histochemistry & Cytochemistry. 44(4): 389-392

Recently, a peroxidase-mediated amplification system has been described for immunofluorescence and fluorescence in situ hybridization studies. It is based on the deposition of hapten- or fluorochrome-labeled tyramide molecules. Although providing a significantly increased detection sensitivity compared to conventional procedures, its localization properties are inferior because of free diffusion of intermediate reaction products before they are immobilized. In enzyme cytochemistry, it is well established that improved localization of enzyme activity can be achieved through the addition of viscosity-increasing polymers to the incubation media. In this study we analyzed the effect of different polymers on the localization sharpness and sensitivity of the tyramide-peroxidase reaction in FISH applications. Significantly improved localization of the fluorescent endproduct was observed using dextran sulfate or polyvinylalcohol (PVA) with, respectively, no or little loss of sensitivity.
