mFluor™ Blue 660 tyramide is a fluorescent labeling reagent used in immunofluorescence staining and in situ hybridization. Tyramide is a small molecule that can diffuse through tissue sections or cell membranes and subsequently be enzymatically amplified to produce a localized, highly fluorescent signal. The mFluor™ Blue 660 dye is conjugated to tyramide to create a fluorescently labeled tyramide that can be used for visualizing specific target molecules or structures within biological samples. mFluor™ Blue 660 tyramide has the largest Stokes Shift among all the commercial tyramide reagents. The high sensitivity and specificity of mFluor™ Blue 660 tyramide make it an excellent choice for fluorescence imaging and detection in various histochemical fluorescence imaging applications.
