IRDye 680LT Infrared Dyes

IRDye 680LT dye is highly soluble in water and is significantly brighter and more photostable than many other 700 nm near-infrared dyes, such as Alexa Fluor® 680. The spectral characteristics of IRDye 680LT are well suited for use on LI-COR imaging systems with absorbance and emission maxima in aqueous solution and methanol of 676 and 693 nm, respectively. IRDye 680LT exhibits low background at near-infrared wavelengths resulting in higher signal-to-noise ratios.

IRDye 680LT dye conjugates can be used for quantitative Western blotting and fluorescence microscopy. When using IRDye 680LT secondary antibodies for Western blot detection, it is critical to follow the recommendations in the pack insert. Dilution optimization may be required to achieve best results.
