Fluorescence Dye 488-I conjugates are significantly brighter than fluorescein conjugates and much more photostable.

• Spectral Equivalent: Alexa Fluor 488, Cy2, DyLight 488, FITC
• Molar Extinction Coefficient: ≥70,000 M^-1cm^-1

The fluorescence of Fluorescence Dye 488-I is not affected by pH between 4 - 10. Compared to Alexa Fluor 488, Fluorescence Dye 488-I of single isomer has much hihger purity, bringing better performance consistancy from batch to batch.
