Descripción

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^™680R is a novel rhodamine-based dye. The dye is highly fluorescent and, more importantly, extremely photostable. Rhodamine dyes are traditionally known to be bright and photostable. However, it has been a synthetic challenge to make functional rhodamine dyes with long wavelengths and high water solubility necessary for bio-labeling. Scientists at Biotium have overcome the challenge and invented a new way to make highly water soluble, bright and photostable rhodamine dyes with wavelengths ranging from red to near-IR. These dyes are excellent for labeling proteins, nucleic acids and small bio-molecules. They are ideal for confocal microscopy, single molecule-based imaging and other applications that demand both brightness and photostability.

Features and Benefits

1. The most photostable 680 nm dye. 2. Suitable for labeling nucleic acids and small bio-molecules. 3. Highly water-solbule and pH-insensitive.

Preparation Note
