Description
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 are far superior 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 alkyne dye is reasonably stable and shows good reactivity and selectivity with azide group for click chemistry applications (CuAAC). The iFluor® 488 dyes are an excellent replacement to the Alexa Fluor® dyes that have identical spectral properties (Alexa Fluor® is the trademark of Invitrogen).
