Description
- Water-soluble, amine-reactive label containing two NHS-ester groups — brightest fluorescent label currently available for the 630-650 nm light sources.
Applications
- Fluorescence imaging
- Fluorescence lifetime applications and fluorescence lifetime imaging (FLIM)
- Superresolution microscopy
- Immunofluorescence and FRET applications
- 2-Photon microscopy
- Single-molecule applications
- Fluorescence correlation spectroscopy (FCS)
- Proteomics
Advantages
- Perfectly suited for excitation with the 635-nm, 647-nm, or 650-nm lasers
- Highly sensitive: high extinction coefficient of 200,000 M–1cm–1 and high quantum yield of ~60% in aqueous environments
- Good aqueous solubility: this label does not alter the solubility of the protein conjugate
- High ozone stability: Higher ozone stability than Alexa Fluor™ 647 or Cy5™ enables array experiments to be performed with SeTau 647 under any environmental condition
- Large Stokes' shift: SeTau647 has a 44 nm Stokes' shift
- Extremely photostable: Much higher photostability as compared to Alexa Fluor™ 647, DyLight 650, ATTO 647N ,or Cy5™ (see below)
- Fluorescence lifetime: 3.1 ns in water - three times longer than that of Cy5™ or Alexa Fluor™ 647
- Ideal for non-radioactive labeling of proteins, amino-modified DNA probes, and amino-modified oligonucleotides
