This reagent is a water-soluble Cy5 dye azide for Click Chemistry.
The dye is bright and photostable, it has red fluorescence. The reagent has high water solubility. Due to high solubility and hydrophilicity, the dye can be used for labeling biomolecules in native, purely aqueous conditions.
The reagent is 1:1 crystallosolvate with methanol. This does not affect any fluorophore properties, and applications.
