Description: Although FITC is still the most popular fluorescent labeling dye for preparing green fluorescent bioconjugates, there are certain limitations with FITC, such as severe photobleaching for microscope imaging and pH-sensitive fluorescence. Protein conjugates prepared with iFluor™ 488 dyes (Ex/Em=491 nm/520 nm) are far superior compared to conjugates of fluorescein derivatives such as FITC. iFluor™ 488 conjugates are significantly brighter than fluorescein conjugates and are much more photostable. Additionally, the fluorescence of iFluor™ 488 is not affected by pH (4-10). This pH insensitivity is a major improvement over fluorescein, which emits its maximum fluorescence only at pH above 9.iFluor™ 488 azide dye is reasonably stable and shows good reactivity and selectivity with alkyne group for click chemistry applications. The iFluor™ 488 dyes are an excellent replacement to the Alexa Fluor dyes that have the identical spectral properties ( Alexa Fluor® is the trademark of Invitrogen).
