Opis ogólny

Far-red fluorescent dyes offer the advantage of ultra sensitive detection because background signal due to autofluorescence in most biological samples is minimal in this spectral region. For many years, the cyanine dye Cy®5 has been the dye of choice for such detection. More recently, Alexa Fluor 647 has been developed as a better alternative by having brighter fluorescence and higher photostability. Despite the improvement, Alexa Fluor 647 still lacks sufficient photostability required for many demanding applications. On the other hand, while Alexa Fluor 633 is photostable, its fluorescence on proteins is very weak. In fact, it has been a challenging task for dye chemists to develop a far-red fluorescent dye that is both highly fluorescent and photostable for protein and nucleic acid labeling. Using new chemistry, scientists at Biotium have successfully developed a series of far-red and near-IR dyes to overcome these challenges. With its absorption peak at 630 nm, CF633 can be optimally excited by the 633 nm He-Ne laser or the 635 nm red diode laser with emission maximum at 650 nm. Despite its shorter emission wavelength, which often is not favored by a Cy®5-based detection window on most instruments, CF633 is still significantly brighter than Alexa Fluor 647. However, for detections using non-laser-based excitation and a Cy®5 filter set, the full advantage of CF633 will not be realized. In this case, we recommend CF640R, another outstanding far-red CF dye that is spectrally closer to Cy®5 or other similar cyanine-based dyes. The most important advantage of CF633 and other rhodamine-based far-red CF dyes are their unmatched photostability. The combination of superior brightness and photostability makes far-red CF dyes ideal choices for detections in the long wavelength region on a variety of instruments.

Cechy i korzyści

1. Yields the brightest anibody conjugates among spectrally similar dyes when excited by the 633 nm He-Ne laser or the 635 nm red diode laser. 2. Far more photostable than Alexa Fluor647. 3. Highly water-soluble.
