HiLyte™ Fluor 647 amine

HiLyte™ Fluor 647 amine is a carbonyl-reactive fluorescent labeling dye that generates the conjugates that are slightly red-shifted compared to those of Cy5 dyes, resulting in an optimal match to filters designed for Cy5 dye. Its conjugate may have better performance than Cy5 for fluorescence polarization-based assays. Extinction Coefficient (M-1cm-1): 250,000 Fluorescence quantum yield: 0.33 Fluorescence Life Time (ns): 1.0
