CyLyte Fluor 7 NHS ester dye has the same organic dye structure as that of Cy®7 NHS ester dye. However, the counter-ion used in the final formulation of AnaSpec’s CyLyte Fluor 7 NHS ester dye does vary compared to the Cy®7 NHS ester dye. The CyLyte Fluor 7 NHS ester is a near infrared amine reactive Cyanine 7 dye. This fluorophore can be used in conjugations for imaging applications in the near infrared region.
