PE-iFluor® 647 Tandem

Tandem dyes are a unique class of fluorescent molecules that consist of two different covalently linked fluorophores, a donor (e.g. PE or APC) and a longer-wavelength emitting fluorescence acceptor (e.g. Texas Red, Cy5, Cy7, iFluor® 594 or iFluor® 750). PE-iFluor® 647 is a superior replacement to the commonly used PE-Cy5 tandem with significantly improved FRET efficiency and signal/background ratio. PE-iFluor® 647 and PE-Cy5® and RPE-Alexa Fluor® 647 Tandem have almost identical spectra. AAT Bioquest also offers a unique preactivated PE-iFluor® 647 to facilitate the PE- iFluor® 647 tandem conjugation to antibodies and other proteins such as streptavidin and other secondary reagents. Our preactivated PE- iFluor® 647 tandem is ready to conjugate, giving much higher yield than the conventionally tedious SMCC-based conjugation chemistry.

Flow cytometry analysis of PBMC stained with PE-iFluor® 647 anti-human CD4 *SK3* conjugate. The fluorescence signal was monitored using an Aurora spectral flow cytometer in the PE-iFluor® 647 specific B8-A channel.
