Key information: IRDye 680RD, NHS ester is a near-infrared (NIR) fluorescent dye, supplied with an NHS ester reactive group for the labeling of primary amines. . Application: Fluorescence microscopy. . Properties and Photophysical Data: Excitation and emission maxima ( ) are 680 nm and 694 nm, respectively. . Please see the protocol for further information on protein/antibody labeling and conjugation. . NOTE : The choice of solvent for the dye is dependent on the stability of the protein in DMSO. Since a small amount of dye is needed to label large (i.e. 45 kDA) proteins, the amount of DMSO in the reaction is negligible and should not affect protein stability. However, since a proportionally larger amount of dye is required to achieve adequate labeling for a small protein (i.e. 45 kDA), the level of DMSO in the reaction is more likely to affect the protein stability. Dye solubilized in water should be discarded after one use. Dye prepared in DMSO is stable for up to two weeks when stored at -20 C and protected from light and moisture. . It is recommended to dissolve dye in water or DMSO (10 - 20 mg/mL) . IRDye is a registered trademark of Li-Cor and is used under license.
