DBCO-S-S-PEG3-biotin 是一种属于 PEG 类的 PROTAC linker，可用于 PROTAC 分子的合成。

DBCO-S-S-PEG3-biotin is a cleavable reagent for introduction of a biotin moiety to azide-containing biomolecules using copper-free Click Chemistry. The disulfide bond in this linker can be cleaved using reducing agents such as DTT, BME and TCEP to remove the biotin label. PEG Linkers can be used in the synthesis of PROTACs.

PROTACs contain two different ligands connected by a linker; one of them is a ligand for an E3 ubiquitin ligase and the other one is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].
