The phospholipid polyethylene glycol alkyne (DSPE PEG Alkyne) can be used to modify proteins, peptides and other materials or small molecules. Alkynyl (- ALK) can react with copper catalyzed azide in aqueous solution. 2-Distearoyl-sn-Glycero-3-Phosphoethanolamine (DSPE) conjugated polyethylene glycol is a combination of phospholipid and polyethylene glycol with hydrophilicity and hydrophobicity. Polyethylene glycol phospholipid liposomes form high-quality materials, which can be used for drug delivery, gene transfection and vaccine delivery. PEGylated phospholipid can significantly improve blood circulation time and stabilize drug encapsulation. These materials can also be used for targeted drug delivery by modifying ligands with target surfaces such as antibodies and peptides.

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.
