Pacific Orange™ dye
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.
