General description
CF™660C and CF™660R are two spectrally similar fluorescent dyes that emit fluorescence at about 685 nm in the borderline spectral region between far-red and near-IR. Although their absorption maxima are at around 660 nm, both dyes can be sufficiently excited by the 633 or 635 nm laser. When combined with other CF™ dyes of shorter wavelengths, CF™660C or CF™660R can serve as a useful long wavelength dye in multi-color detection applications. The two dyes are spectrally similar to Alexa Fluor™ 660 but are far superior to the latter in performance. Like Alexa Fluor™ 660, CF™660C is a cyanine-based dye. However, when conjugated to protein, CF™660C is several fold brighter and significantly more photostable than Alexa Fluor™ 660.
Features and Benefits
1. Much brighter than Alexa Fluor™660. 2. More photostable than Alexa Fluor™660. 3. Highly water-soluble.
Preparation Note
Protect from light
Dissolve in DMSO
