General description

18:0 PEG750 PE is a polyethylene glycol (PEG) conjugated phospholipid. The molecular weight and exact mass are averages based on the polydispersity of PEG.


18:0 PEG750 PE might be used to PEGylate lipoplexes and to study the feasibility of its entrapment into a solid matrix system for prolonged delivery of siRNA in vaginal mucus.

Biochem/physiol Actions

18:0 PEG750 PE is useful as a micelle-forming component.

Cell-penetrating peptide (TATp) was attached to the distal tips of polyethyleneglycol (PEG) moieties of polyethyleneglycol-phosphatidylethanolamine (PEG-PE) micelles loaded with paclitaxel (PCT). The TATp-modified micelles demonstrated an increased interaction with cancer cells compared to non-modified micelles resulting in a significant increase...
