ATTO Rho11 Fluorescent Dye Oligonucleotide Labeling
Bio-Synthesis offers ATTO Rho11 fluorescent dye oligonucleotide labeling services. ATTO Rho11 is a fluorescent label related to the class of Rhodamine dyes. This label have very hihg fluorescence efficiency and photostability. It's excitation range is 550-580nm. thisdye can be use as an alternative dye for ROX dye.
Features:
- Replacement dye for ROX
- Excitation range: 550-580 nm
- High fluorescence yield
- High thermal and photo-stability
- Cationic dye
ATTO Rho11 dye 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 used to remove failure sequences during first HPLC purification, after labeling, the second HPLC is performed to remove unlabeled oligonucleotides and excessive dye in order to obtain a full length labeled oligonucleotide.

-20°C To -70°C
Oligonucleotides are stable in solution at 4°C for up to 2 weeks. Properly reconstituted material stored at -20°C should be stable for at least 6 months. Dried DNA (when kept at -20°C) in a nuclease-free environment should be stable for years.
