StarBright Yellow Dyes

Coming soon - Excitable by the 561 nm laser, StarBright Yellow (SBY) Dyes, are perfect to replace existing dyes in your flow cytometry panels and expand your capabilities across the yellow laser.

Designed to be bright enough to resolve most populations, with reduced excitation by the 488 nm laser, compared to PE and PE-tandems, StarBright Yellow Dyes should be your first choice in panel design.

StarBright Yellow Dyes are the perfect replacements for PE and PE-tandems in your flow cytometry experiments. Bright, with reproducible unique spectra that can be fixed in PFA or alcohol-based fixatives with minimal performance changes, these dyes are suitable for both conventional and spectral flow cytometry (Figure 2).

With reduced excitation by the 488 nm laser compared to PE and PE tandems, StarBright Yellow Dyes have reduced spillover and spreading, giving you better resolution in multicolor panels.

StarBright Yellow Dyes can be used successfully in combination with other StarBright Dyes and traditional fluorophores. Figure 3 shows how they can be used to identify common and rare subsets including naïve and memory status in human peripheral blood.

Fig. 3. Immunophenotyping panel including StarBright Yellow Dye conjugated antibodies. Red blood cell lysed human peripheral blood was stained with 11 antibodies and a L/D marker. StarBright Yellow Dyes used in this panel were SBY575, SBY605, SBY665, and SBY800. Cells were also gated on live, single cells (not shown).
