Targeted and specific labeling of amine functional groups on antibodies, peptides or oligonucleotides Bulk packs available for maximum economy Example protocols included with each fluorescent dye pack Narrow excitation and emission bands result in discrete signals from each fluor Minimal crosstalk provides high accuracy and enables multiplexing High purity CyDye fluors readily dissolve in aqueous buffers. They are ideal for fluorescent labeling in applications such as ELISAs, immunoprecipitation, and other assays.
