Tyramide signal amplification. In brief, the hapten-labeled probe is hybridized to the target RNA, and then fluorescent TSA utilizes the enzymatic catalysis of horseradish peroxidase and fluorescently labeled tyramide substrates, depositing highly dense tyramide species at the site of enzyme activity (27).Cited by: The chromosome that is labeled with green and red spots (upper left) is the one where the rearrangement is present. Fluorescent in situ hybridization (FISH) is a molecular cytogenetic technique that uses fluorescent probes that bind to only those parts of the chromosome with a high degree of sequence complementarity. Aug 11,  · TSA-FISH is a multistep procedure consisting of in situ hybridization with a biotinylated probe, the detection of the hybridized target with streptavidin-horseradish peroxidase, and signal amplification with fluorescent dye-conjugated tyramide (Fig. 1).Cited by: 2.
