Biotinylation reagent with Azide, and a long 11 PEG spacer. Labels terminal alkynes via a copper-catalyzed “click reaction". Useful for labeling fluorescent dyes with triple bond alkyne groups.

≥96%

Soluble in DMSO. Limited solubility in water. Preferably, stock solutions should be made in DMSO, then diluted in to aqueous solutions.

White to off-white solid. May appear sticky.

Store at or below ≤4°C. Solid form is stable at least 2 years from date of receipt, when stored as directed.

Useful for biotinylation of fluorescent dyes or other compounds with triple bond alkynes via click chemistry.

Protect from moisture. Store with desiccant.
