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.
IRDye 680LT NHS Ester
IRDye infrared dyes from LI-COR Biosciences are available for researchers developing applications using near-infrared (NIR) fluorescence.
Standard NHS ester chemistry is used to produce custom probes labeled with LI-COR IRDye infrared dyes. The NHS ester reactive group provides the functionality for labeling primary and secondary amines, such as lysine residues in proteins.
Chemical Formula: C54H52N3Na3O22S6
Molecular Weight: 1402.32 g/mol
Exact Mass: 1401.09
IRDye 680LT Maleimide
IRDye 680LT Maleimide will label molecules with free sulfhydryl (–SH) groups, such as cysteine residues in proteins. Conjugation can be performed at physiological pH.
Chemical Formula: C56H55N5Na5O21S6
Molecular Weight: 1427.37 g/mol
Exact Mass: 1426.12
Note: IRDye 680LT dye products should not be used for small animal in vivo imaging or In‑Cell Western™ Assays. The higher level of fluorescent intensity creates high background making it unfavorable for use in these applications. We recommend using IRDye 680RD dye products for these applications.
