CyDye Mono-Reactive NHS Ester Fluorescent Dyes are intensely fluorescent and highly water soluble, providing significant advantages over other existing fluorophores.

• Store refrigerated at 2–8°C in the dark.
• Reconstitute the material to 1 mg/mL in anhydrous DMF/DMSO. Reconstituted material may be stored for up to 2 weeks at -200°C in aliquots to avoid repeat freeze thaw cycles.
• The CyDye supplied here are monofunctional NHS esters, and are provided in a dried, pre-measured form ready for the labeling of compounds containing free amino groups.
