Cambridge Bioscience offers a series of highly water-soluble fluorescent dyes spanning the visible and near-infrared (NIR) spectrum. Ideal for labeling biomolecules, especially proteins and nucleic acids, our CF™ dye range rivals or exceeds the brightness of other commercially available dyes, are highly pH insensitive and offer the highest level of photostability.
Benefits of using CF™ Dyes
• Superior photstability
• Exceptional brightness
• Suitable for in vivo imaging
• Unrivaled NIR dyes
• High specificity
• Highly pH insensitive
• Excellent labelling efficiency
• Multicolour flexibility
• Ideal antibody conjugates

Cambridge Bioscience offers a range of CF™ Dye comprising 20 fluorophores spanning the EM spectrum from UV to near IR. The CF™ dyes rival or exceeds the brightness of other commercially available dyes and are highly pH insensitive whilst boasting amongst the highest photostability available. The dyes are particularly useful as antibody conjugates because they are less highly charged than many other available dyes ensuring they have a reduced impact upon the protein isoelectric point which is known to affect target specificity.
Benefits of using CF™ Dyes
