Orange fluorescent reagent widely used for tyramide signal amplification (TSA) in IHC, ICC, ISH, FISH and multicolor FISH. HRP catalyzes localized deposition of multiple tyramide molecules (catalyzed reporter deposition, CARD), binding the fluorescein tyramide to adjacent tyrosines to enhance fluorescent signal.
