Description
- Hydrophilic, thiol-reactive, long-lifetime label containing one maleimide group, with one positive charge and chloride as the counter-ion.
Applications
- Covalent labeling of proteins, thiol-modified DNA, thiol-modified oligonucleotides and lipids.
- Fluorescence lifetime assays.
- Fluorescence polarization-based assays of high molecular weight antigens.
Advantages
- Highly fluorescent label for proteins and oligos.
- High quantum yield (Q.Y.) ~ 51 % (water).
- Long fluorescence lifetime of 9 ns in water.
- Perfectly suited for excitation with the 380-nm and 404-nm diode lasers .
- Large Stokes' shift of over 100 nm.
- High fundamental polarization P0 = 475 mP.
- Highly soluble in aqueous buffer (500 mg/L at 20°C).
