Features and Benefits

Biotin-dPEG®7-azide is a single molecular weight dPEG® that permit biotin labeling with precise spacing to molecules containing an alkyne using well-known, highly popular click chemistry. By inserting an alkyne function into the target molecule, site specific labeling can occur using either copper(I) catalyzed or strain-catalyzed click chemistry. The single molecular weight nature of the dPEG® spacer (30.7 Å) allows the user to precisely tailor the distance between the biotin and the target molecule in order to receive optimal binding between biotin and avidin.
