CF™660C & CF™660R

Cambridge Bioscience offers two fluorescent dyes spectrally similar to Alexa Fluor® 660 but with far superior performance. CF™660C protein conjugates are several-fold brighter than Alexa Fluor® 660. In comparison, CF™660R is exceptionally photostable, making it ideal for confocal microscopy and other demanding applications.CF™660C and CF™660R are two spectrally similar fluorescent dyes that emit fluorescence at about 685nm in the borderline spectral region between far-red and near-IR .

CF™660C Technical Details
• 667/685 nm Abs/Em Maxima
• 200,000 Extinction Coefficient
• ~ 3112 Molecular Weight
• 633 nm, 635 nm or 640 nm Excitation Laser Line
• Direct Replacement For Alexa Fluor® 660, Allophycocyanin (APC)

CF™660R Technical Details
• 663/682 nm Abs/Em Maxima
• 100,000 Extinction Coefficient
• ~ 888 Molecular Weight
• 633 nm, 635 nm or 640 nm Excitation Laser Line
• Direct Replacement For Alexa Fluor® 660, Allophycocyanin (APC)

Benefits Of Using CF™660C & CF™660R
• CF™660C much brighter & more photostable than Alexa Fluor® 660
• CF™660R brighter than Alexa Fluor® 660 most photostable 660 nm dye ideal for confocal microscopy applications
• CF™660C & CF™660R highly water-soluble

Fluorescence Intensity Comparison

CF660Relative fluorescence of CF™660, CF™660R and Alexa Fluor 660 (AF660) goat anti-mouse conjugates as a function of the number of dye molecules per protein (degree of labeling).

Photostability Comparison
CF660 2Photostability of CF™660C, CF™660R, and Alexa Fluor® 660 (AF660) goat anti-mouse conjugates. HeLa cells were stained with mouse anti-tubulin followed by CF™660C, CF™660R or AF660 goat anti-mouse IgG conjugates. Cells were continuously exposed to mercury arc lamp microscope excitation using a Cy™5 filter set. Images were captured every 10 seconds for five minutes and fluorescence intensity was normalized to time 0.
