IRDye 800 RS is the dye of choice for nucleic acid applications. The NHS ester reactive group provides the functionality for labeling primary and secondary amino groups. Nucleic acids labeled with this dye are easily purified with reverse-phase chromatography. The dye has good water solubility, but low salt tolerance, and is more hydrophobic than IRDye 800CW. This dye is not recommended for most protein applications.
