Pacific Orange dye is a bright orange-fluorescent dye optimally excited by the 405 nm line of the violet laser and with excitation/emission at 400/551 nm. Conjugates of this dye are strongly fluorescent even at neutral pH.
Pacific Blue, Pacific Green and Pacific Orange dye conjugates can be simultaneously excited at 405 nm and emit at 455 nm, 500 nm and 551 nm, respectively, facilitating three-color analysis.
We offer Pacific Orange dye conjugated to a variety of primary antibodies, secondary antibodies and streptavidin. In addition, reactive and protein labeling kits are available so that you can produce your own antibody conjugates or probes.

Violet laser–compatible antibody conjugates
We offer Pacific Blue, Pacific Green and Pacific Orange dyes as well as Qdot probes for use with the violet laser. In addition to primary and secondary antibody conjugates of these dyes, we’ve developed kits for cell proliferation, immunophenotyping, dead cell discrimination, apoptosis, and cell cycle analysis—all aimed at helping you maximize the data you can get from your violet laser–equipped flow cytometer.
