General description
CF™680 and CF™680R are two outstanding near-IR dyes excitable at about 680 nm with emission at about 700 nm. The two dyes each have unique properties suitable for different application needs. CF™680 is a highly water-soluble cyanine-based dye with a molecular weight of ~3000. This dye is excellent for labeling antibodies, producing the brightest fluorescence and highest signal-to-noise ratio in immunostaining among spectrally similar dyes, such as Cy®5.5, Alexa Fluor™ 680, DyLight® 680 and IRDye® 680. However, because of its relatively large molecular size, CF™680 is not recommended for labeling nucleic acids or relatively small biomolecules, for which our CF™680R is better suited.
Features and Benefits
1. The brightest among spectrally similar 680 nm dyes. 2. Superior signal-to-noise ratio in immunostaining. 3. Highly water-soluble and pH-insensitive.
Preparation Note
Dissolve in DMSO
Protect from light and moisture
