Exclusively from Beckman Coulter, our new organic fluor, Krome Orange™ dye, maximizes the potential of your violet laser. Krome Orange dye has been optimized for superior optical performance including high signal to noise ratios and minimal intra-laser compensation requirements.
Krome Orange dye has been optimized for superior optical performance including high signal to noise ratios and minimal intra-laser compensation requirements.
- Narrow, well separated emission profiles
- Excited by violet laser; optimally detected using a 550/40 filter
- Virtually no excitation detected using a 488 nm laser

Krome Orange dye is at least as bright as Horizon™ V500 dye and can provide more than twice the population separation obtained with Pacific Orange™ dye conjugates and with little compensation versus Pacific Blue™ dye.
- Less compensation than Horizon V500 dye versus Pacific Blue dye
- Unlike AmCyan, essentially no compensation versus 488-excited channel
- Better population resolution than Pacific Orange dye
Krome Orange dye is optimally suited to deliver exceptional performance on instruments equipped with a violet laser.
