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

• Store refrigerated at 2 to 8 °C in the dark
• Reconstitute the material to 1 mg/ml in anhydrous DMF/DMSO
• Reconstituted material may be stored for up to two weeks at −20 °C in aliquots to avoid repeat freeze thaw cycles
• Produces an intense signal easily detected using most rhodamine filter sets in the appropriate instrumentation

The Cydyes supplied here are monofunctional NHS-esters, maleimides or hydrazides and are provided in a dried, pre-measured form ready for the labelling of compounds containing free amino groups, thiol groups or carbonyl groups. The Cy3B dye is orange fluorescing cyanine that produces an intense signal easily detected using most rhodamine filter sets in the appropriate instrumentation.
