PE-iFluor® 660 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® 660 is a new unique tandem color for multicolor applications, in particular, for designing spectral flow cytometric panels. It has been validated with Cytek’s Aurora flow cytometer. AAT Bioquest also offers a unique preactivated PE-iFluor® 660 to facilitate the PE-iFluor® 660 tandem conjugation to antibodies and other proteins such as streptavidin and other secondary reagents. Our preactivated PE- iFluor® 660 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-iFlour® 660 anti-human CD4 *SK3* conjugate. The fluorescence signal was monitored using an Aurora spectral flow cytometer in the PE-iFluor® 660 specific B9-A channel.
