Figure 1. iFluor® 670 dyes have fluorescence excitation and emission maxima of ~670 nm and ~690 nm respectively. These spectral characteristics make them a unique acceptor for preparing PE, APC and PerCP tandems that are widely used in flow cytometry applications. iFluor® 670 dyes have excellent photostability. iFluor® 670 Maleimide is stable and shows good reactivity and selectivity with protein thiol group.
