The DyLight Dyes exhibit higher fluorescence intensity and photostability than Alexa™, CyDye™ and LI-COR™ Dyes in many applications and remain highly fluorescent over a broad pH range (pH 4-9). Additionally, the water solubility of the DyLight Dyes allows a high dye-to-protein ratio without precipitation during conjugation.


  • Brightness: high-fluorescence intensity provides outstanding sensitivity and requires less conjugate

  • Photostability: exceptional resistance to photobleaching enables fluorescence imaging under the most demanding conditions (e.g., structured illumination, 4pi microscopy)

  • Instrument compatibility: emission spectra match the principal output wavelengths of common fluorescence instrumentation
