DSPE-PEG-CHO ammonium (MW 2000)

DSPE-PEG-CHO ammonium (MW 2000) is a linear heterobifunctional PEGylation reagent composed of DSPE phospholipids and aldehyde groups. The PEG linker offers excellent hydrophilicity and water solubility. Aldehyde polyethylene glycol (DSPE) is commonly used as a reactive phospholipid for conjugating antibodies, peptides, or other ligands to the surface of liposomes and other lipid PEG nanoparticles. DSPE-PEG-CHO ammonium (MW 2000) is applicable for drug delivery.
