产品描述:一种生物素标记的 PROTAC linker,属于 PEG 类。可用于合成 PROTAC 分子。Biotin-PEG4-alkyne is a PEG derivative containing a biotin group and an alkyne group. The alkyne group can react with azide moiety in Cu(I)-catalyzed 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.
