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 a 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
