- Description
- Fluorinated fluorescent dye. Increased resistance to photobleaching and higher quantum yields makes it a superior fluorescent dye. Pacific Blue dyes yield conjugates that are strongly fluorescent, even at neutral pH. Spectral data: Extinction 403nm/Emmission 455nm. The amine-reactive succinimidyl ester derivative can be used to create bright blue-fluorescent bioconjugates with excitation/emission maxima ~410/455 nm that are excitable by the 405 nm spectral line of the blue diode (violet) laser.
