Fluorophores for the UltraViolet (355 nm) Laser

Bio-Rad has new StarBright Dyes that are excitable by the ultraviolet (355 nm) laser and suitable for both conventional flow cytometry and spectral flow cytometry. Table 1 shows the excitation and emission maxima, the relative brightness, and ZE5 Cell Analyzer filter which allows detection. As other instruments may have different filters, please check compatibility on your instrument before you start your experiment.

StarBright UltraViolet 400 Dye (ex 335/em 395)


StarBright UltraViolet 400 Dye is part of the StarBright Dye range, a new range of fluorescent nanoparticles specifically designed for flow cytometry to be bright with narrow excitation and emission profiles. Excitable by the ultraviolet, 355 nm laser and emitting at 395 nm, this bright fluorophore is the ideal dye to replace BUV395 giving you more choice and flexibility when multicolor panel building.

StarBright UltraViolet 445 Dye (ex 347/em 440)


StarBright UltraViolet 445 Dye is part of the StarBright Dye range, a new range of fluorescent nanoparticles specifically designed for flow cytometry to be bright with narrow excitation and emission profiles. Excitable by the ultraviolet, 355 nm laser and emitting at 440 nm, this bright fluorophore is unique in that it is up to 20x brighter than AF350 and there are no polymer dyes that emit at a similar wavelength.

StarBright UltraViolet 510 Dye (ex 340/em 513)


StarBright UltraViolet 510 Dye is part of the StarBright Dye range, a new range of fluorescent nanoparticles specifically designed for flow cytometry to be bright with narrow excitation and emission profiles. Excitable by the ultraviolet, 355 nm laser and emitting at 513 nm, this fluorophore is brighter than BUV496 and is not a traditional tandem dye giving you more choice and flexibility when multicolor panel building.
