IRDye® 680LT NHS Ester (0.5 mg)

206,40

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.
