Cholesterol-PEG-Amine, MW 5,000 is a PEG lipid designed for drug delivery and bioconjugation applications. The cholesterol moiety enhances membrane interaction and encapsulation of hydrophobic drugs, while the terminal amine reacts with NHS esters to form stable amide linkages. The 5k polyPEG spacer improves aqueous solubility, stability, and biocompatibility, making it ideal for lipid nanoparticle (LNP) formulations, targeted delivery systems, and advanced therapeutic research.
