6-FAM-PEG3-Azide is a fluorescent labeling reagent composed of a 6-carboxyfluorescein (6-FAM) dye linked to an azide via a PEG3 spacer. It is designed for covalent conjugation to alkyne-functionalized partners using copper-catalyzed azide-alkyne cycloaddition (CuAAC) or strain-promoted azide-alkyne cycloaddition (SPAAC), enabling fluorescent labeling of oligonucleotides and other biomolecules.
- Fluorescent labeling with excitation 498 nm and emission 532 nm.
- PEG3 spacer improves water solubility and reduces steric hindrance.
- Azide functional group for CuAAC and SPAAC click chemistry.
- Solid, light yellow to yellow form stable when stored as powder at -20°C.
- High purity (~98.1%) suitable for analytical and labeling applications.
