Description

Cholesterol-PEG-Amine (CLS-PEG-NH2, Cholesterol-PEG-NH2, Cholesterol functionalized polyethylene glycol with amine) uses very stable chemical bonds/linkage to attach cholesterol and amine to PEG through ether bond or amide bond. Unlike ester bonds which are prone to hydrolysis in aqueous solution, the ether linkage between cholesterol and PEG is chemically robust and very stable. Cholesterol is a membrane constituent which serves a unique function of modulating membrane fluidity, elasticity, and permeability. It fills in the gaps created by packing of other lipid species when proteins are embedded in the membrane. PEGylated cholesterol as an amphiphilic lipid derivative can be used to prepare liposome and other micelles as drug delivery systems. In addition to mPEG-cholesterol, reactive or dye labeled PEG-cholesterol reagents may be offered through custom synthesis with a short turnaround.
