HiLyte™ Fluor 594, an alternative to Alexa Fluor™ 594 and DyLight Fluor™ 594, has spectral characteristics similar to those of Texas Red. The labeling performance and stability are better than those of Texas Red. It has high extinction coefficient (80,000 M-1cm-1), high fluorescence quantum yield (0.9) and low correction factor (0.17). HiLyte™ Fluor594 based Bioconjugates exhibit little spectral overlap with green-fluorescent conjugates, and can be efficiently excited by 568 nm line of Ar-Kr laser and by the 594 nm line of orange He-Ne laser.Extinction Coefficient (M-1cm-1): 80,000Fluorescence quantum yield: 0.90Fluorescence Life Time (ns): 4.2
