Pacific Blue dye i

Invitrogen Molecular Probes 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.

Invitrogen products such as 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.

Violet laser–compatible antibody conjugates

We offer Pacific Blue, Pacific Green and Pacific Orange dyes as well as Invitrogen 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.
