HiLyte Fluor 488 acid, SE

HiLyte Fluor 488 acid, SE is an excellent amine-reactive fluorescent labeling dye that generates the protein conjugates far superior to those of fluorescein derivatives such as FITC. Not only are HiLyte Fluor 488 conjugates significantly brighter than fluorescein conjugates, they are much more photostable. Additionally the fluorescence of HiLyte Fluor 488 fluorophore is independent of pH from 4 to 10. This pH insensitivity is a major improvement over fluorescein, which emits its maximum fluorescence only above pH 10. Extinction Coefficient (M-1cm-1): 70, 000 Fluorescence quantum yield: 0.91 Fluorescence Life Time (ns): 4.1
