Description

Highly hydrophilic, viscosity-sensitive, thiol-reactive label containing one maleimide group.

Covalent labeling of proteins, thiol-modified DNA, and thiol-modified oligonucleotides
Viscosity-sensitive label for probe environment
Viscosity-sensitive fluorescence lifetime label — this label exhibits a distinct lifetime change upon changing the viscosity of the environment

Perfectly suited for excitation with the UV and blue light sources, such as the 330-nm, 436-nm, and 470-nm LEDs and diode lasers
Large Stokes' shift
Viscosity-related changes in Q.Y. and lifetime
pH-insensitive between pH 3 and pH 10
Good aqueous solubility
Ideal for non-radioactive labeling of proteins, thiol-modified DNA probes, and thiol-modified oligonucleotides
