Bio-Synthesis offer Dansyl fluorescent dye oligonucleotide labeling services. Dansyl is an environment-sensitive fluorescence dye with large strokes shift. I has peak excitation wavelength in 489 nm and emission wavelength in 526 nm.

Dansyl can be incorporated at any position within an Oligonucleotide. A primary amine modified oligonucleotide is used to covalently attach with dye via NHS conjugation chemistry; other cross-linking chemistries are also available depending on particular project specifications. Dual HPLC purification is highly recommended.
