Description
Structure Excitation and emission spectra of unconjugated Cy5 dye in phosphate buffered saline.PropertiesExcitation maximum (nm)：646Emission maximum (nm) ：664Extinction coefficient (M-1 cm-1)：250000Quantum yield：0.27Fluorescence lifetime (ns)：1.0Upon attachment to biomolecules (for example oligonucleotides), negligible shifts in excitation and emission wavelength have been observed. In addition no effects on these spectral characteristics have been observed in the presence of 10% DMSO or under a range of pH conditions
