HiLyte Fluor™ 555 acid, SE is an excellent amine-reactive fluorescent labeling dye that generates the protein conjugates that are only slightly red-shifted compared to those of Cy3 dyes, resulting in an optimal match to filters designed for Cy3 dyes.
HiLyte Fluor™ 555 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.
