PE-iFluor® 594 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® 594 is a superior replacement to the commonly used PE-Texas Red tandem with significantly improved FRET efficiency and signal/background ratio. Its primary absorption peak is at 565 nm with emission peak around 610 nm. AAT Bioquest also offers a unique preactivated PE-iFluor® 594 to facilitate the PE- iFluor® 594 tandem conjugation to antibodies and other proteins such as streptavidin and other secondary reagents. Our preactivated PE- iFluor® 594 tandem is ready to conjugate, giving much higher yield than the conventionally tedious SMCC-based conjugation chemistry. In addition, our preactivated PE tandems are conjugated to a protein via its amino group that is abundant in proteins while SMCC chemistry targets the thiol group that has to be regenerated by the reduction of antibodies.

Top) Spectral pattern was generated using a 4-laser spectral cytometer. Spatially offset lasers (355 nm, 405 nm, 488 nm, and 640 nm) were used to create four distinct emission profiles, then, when combined, yielded the overall spectral signature. Bottom) Flow cytometry analysis of whole blood stained with PE/iFlour® 594 anti-human CD4 *SK3* conjugate. The fluorescence signal was monitored using an Aurora spectral flow cytometer in the PE/iFluor® 594 specific B6-A channel.

Stain index comparison of CD4+ signal using fluorophore-labeled antibody conjugates. Human peripheral blood mononuclear cells (PBMCs) were isolated and stained using AAT Bioquest PE/iFluor® 594 anti-human CD4 conjugates or Biolegend PE/Dazzle™ 594 anti-human CD conjugates. The fluorescence signal was monitored using an Aurora spectral flow cytometer in the PE/iFluor® 594 specific B6-A channel.
The fluorescence intensity of PE-iFluor® 594 anti-human CD4 *SK3* conjugate at different concentrations in the range of 0.03125 to 0.5 µg. Results showed that the fluorescence intensity of the CD conjugates remained nearly consistent.
