About
Fluorescein Tyramide
Fluorescein Tyramide is a green fluorescent reagent widely used for tyramide signal amplification (TSA) in IHC, ICC, 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. Under the same conditions, iFluor® 488 Styramide is a superior replacement with higher sensitivity and faster reaction speed. In addition, iFluor 488 is much more photostable, and tolerate much broad pH ranges.
