4-ARMPEG-CLS (4-Arm PEG-Cholesterol) is a highly specialized, multi-arm PEG derivative engineered for advanced biomaterials research and targeted drug delivery. Structurally, it consists of a central core branching into four PEG arms, each terminating with a hydrophobic cholesterol molecule. This unique architecture integrates the excellent water solubility and biocompatibility of PEG with the membrane-interacting properties of cholesterol, making it a valuable material for drug delivery, lipid nanoparticle (LNP) development, nanomedicine, and biomaterial research. 

Biopharma PEG offers a wide range of PEG linkers on both lab and commercial scales. Email at [email protected] and start using a superior product for your next product R&D project.
