NHS PEG DSPE can be easily incorporated into liposomes and other nanoparticles through the reaction of NHS with amine. DSPE peg NHS is one of the most commonly used reactive phospholipids that bind antibodies, proteins, peptides or other substrates to the surface of liposomes and other lipid peg nanoparticles. Pegylated phospholipids have longer blood circulation time and higher encapsulation molecular stability. We have developed a series of chemically reactive phospholipid peg products with high purity, various molecular weights and excellent chemical reactivity. These lipid peg conjugates exhibit excellent amphiphilic properties and provide superior advantages for the modification, preparation and transportation of small and large molecules.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
