IRDye® 680LT NHS Ester (0.5 mg)

€171,20

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.

 

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.

IRDye® 800CW NHS Ester reaction
NHS Ester reacts with a primary aliphatic amine, such as lysine.
IRDye® 800CW NHS Ester amide bond
Dye label is attached through amide bond.
