DOPE-mPEG, MW 2000

DOPE-mPEG, MW 2000 is a phospholipid polydisperse PEG (or DOPE liposome), can be used for preparation of targeted delivery of liposomal drug and giant unilamellar vesicles (GUVs). DOPE-mPEG, MW 2000 significantly reduces the pH-sensitivity of the liposome in a concentration dependent manner[1][2][3].
