CY5 is a novel and potent photoswitchable fluorescent labeling reagent and reactive dye used for labeling of amino-groups in peptides, proteins, and oligonucleotides. It requires small amount of organic co-solvent (such as DMF or DMSO) to be used in labeling reaction. This reagent is ideal for very cost-efficient labeling of soluble proteins, as well as all kinds of peptides and oligonucleotides. This reagent also works well in organic solvents for small molecule labeling.Excitation (nm):649, Emission (nm): 670.
