Biotin-PEG4-Alkyne is non-cleavable, alkyne-activated biotinylation reagent that can be reacted with azides via a copper-catalyzed click reaction enabling efficient and specific conjugation of derivatized molecules in biological samples. The hydrophilic polyethylene glycol (PEG) spacer provides a long and flexible connection that minimizes steric hindrance involved with binding to avidin molecules.
