14:0 PEG2000 PE

1,2-dimyristoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] (ammonium salt)

14:0 PEG2000 PE

14:0 PEG2000 PE, also known as 1,2-dimyristoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] (ammonium salt), is a polyethylene glycol (PEG)-phospholipid conjugate in the polymerizable lipid category. It plays a pivotal role in vesicle formulation by preventing aggregation from peptide addition, which ensures stable and functional vesicles.


14:0 PEG2000 PE is instrumental in the preparation and formation of giant vesicles, enabling researchers to explore cellular processes and membrane dynamics precisely and accurately. Additionally, incorporating 14:0 PEG2000 PE in lipid nanoparticle formulations enhances stability and efficacy, facilitating advanced drug delivery systems.

It has also been used to prepare unilamellar liposomes for small-angle X-ray scattering (SAXS) experiments, helping investigate molecular structures and interactions with greater clarity and detail.


Soluble in ethanol, DMSO, and chloroform-methanol at 5mg/mL.


Avanti Research offers 14:0 PEG2000 PE in 25 mg, 200 mg, 500 mg, and 1 g powder packaging options. With over 50 years in business, Avanti Research is the trusted leader in lipid-based products that save and improve lives. We are the premier choice for polymerizable lipids for research and development purposes.
