Biotin-tyramide
Biotin-tyramide is used for tyramide signal amplification (TSA) which is a powerful, patented technology that significantly enhances both chromogenic and fluorescent signals. TSA is easily integrated into standard nonradioactive in situ hybridization (ISH) or IHC protocols.
TSA is an enzyme-mediated detection method that uses horseradish peroxidase (HRP) to catalyze the deposition of a fluorophore-labeled tyramide amplification reagent onto tissue sections or cell preparation surfaces that have been previously blocked with proteins.
Biotin-tyramide use horseradish peroxidase (HRP) to catalyze covalent deposition of biotin labels directly adjacent to the immobilized enzyme. The labeling reaction is quick (less than 10 minutes) and deposited labels can be detected with streptavidin conjugates for imaging in brightfield or fluorescence microscopy.
