HiLyte Fluor™ 555 hydrazide is a carbonyl-reactive fluorescent labeling dye that generates the conjugates that are only slightly red-shifted compared to those of Cy3 dyes, resulting in an optimal match to filters designed for Cy3 dyes. It can be used for labeling glycoproteins such as HRP. HiLyte Fluor™ 555 dye is more photostable than Cy3, providing researchers with additional time for image capture. Additionally, our in-house data indicated that HiLyte Fluor™ 555 is superior to Cy3 in fluorescence polarization-based assays.
