AAT Bioquest iFluor® 488 succinimidyl ester

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 SE dye is reasonably stable and shows good reactivity and selectivity with protein amino groups. This iFluor® 488 has spectral properties and reactivity similar to Alexa Fluor® 488 NHS ester.
