PEG lipids, also known as PEGylated lipids, are a class of PEG derivatives. PEG lipids have been widely used to improve the circulation time of liposome-encapsulated (LNP) drugs and reduce nonspecific uptake. The design flexibility of PEG lipids and the simplicity of physical drug entrapment make PEG-lipid micelles a versatile and effective drug carrier for cancer therapy. They have been shown to overcome some of the limitations of poorly soluble drugs, such as non-specific biodistribution and targeting, lack of water solubility, and poor oral bioavailability. CD Bioparticles offers a wide range of polyethylene glycol-lipid conjugates, including various functionalized polyethylene glycol ends such as amines, carboxylic acids, azides, aldehydes, thiols and hydroxyls. In addition, we also provide a choice of different lipids, such as Cholesterol, DOPE, DSPE, and DBCO, etc.
