Pacific Blue™ dye
Pacific Blue™ dye is a bright blue-fluorescent dye optimally excited by the 405 nm line of the violet laser and with excitation/emission at 410/455 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 Blue™ dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection. In addition, reactive dyes and protein labeling kits are available so that you can produce your own antibody conjugates or probes.
