DBCO-PEG4-biotin is a PEG analogue containing a biotin group and an alkyne group. The alkyne group can react with azide moiety in copper-free Click Chemistry reaction to form a stable triazole linkage. The hydrophilic PEG spacer increases solubility in aqueous media and increases membrane impermeability of the molecules conjugated to the biotin compound. It also helps to minimize steric hindrance involved with the binding to avidin molecules. References: Deng CY, Long YY, Liu S, Chen ZB, Li C.
