Biotin-PEG4-azide is a very useful biotinylation reagent that enable Click Chemistry reaction with alkyne, such as Propargyl, DBCO or BCN reagent to form a stable bond. PEG4 spacer increases aqueous solubility of the molecules conjugated to the biotin. It also helps to minimize steric hindrance involved with the binding to avidin molecules.
