Description
Highly hydrophilic, viscosity-sensitive, amine-reactive label containing one NHS-ester group
Applications
Assessment of viscosity of probe environment — see [
31
]
Covalent labeling of proteins, amino-modified DNA and amino-modified oligonucleotides
Viscosity sensitive fluorescence lifetime label — this label exhibits a distinct lifetime change upon changing the viscosity of the environment
Advantages
Perfectly suited for excitation with the 330, 436, and 470-nm diode lasers and UV light
Large Stokes' shift
pH-insensitive between pH 3 and pH 10
Good aqueous solubility; this label does not alter the solubility of the protein conjugate
High photostability
