iFluor™ 488 alkyne

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 the identical spectral properties.
