Polyethylene Glycol (PEGs & PEOs)

m-PEG12-CH2CH2NHCH2CH2COOH is a PEG derivative containing a terminal carboxylic acid. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond. The hydrophilic

m-PEG12-DSPE is a PEG derivative with a DSPE moiety. The DSPE-PEGs have been FDA approved for medical applications. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The hydrophilic PEG
