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-PEG6-Maleimide is a PEG derivative containing a biotin group and a maleimide group for labeling and crosslinking cysteines and other sulfhydryls. The maleimide group reacts specifically with sulfhydryl groups (at pH 6.5-7.5) to form a stable, irreversible thioether 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.
