Product overview

Description & Application

DSPE-PEG-OPSS, DSPE (1,2-distearoyl-sn-glycerol-3-phosphoethanolamine) is a saturated 18 carbon phospholipid, commonly used in the synthesis of liposomes. Polyethylene glycol (PEG) - coupled DSPE is hydrophilic and can be used for drug delivery, gene transfection and biomolecular modification. The PEG of phospholipid significantly improved the blood circulation time and stability of the capsule drug. Polyethylene glycol can enhance the solubility and stability, reduce the non-specific binding of charged molecules on the surface, and reduce the immunogenicity of polypeptides. Mercaptopyridine reacts with mercapto group to release pyridine ring and generate stable disulfide bond.

Handling guidance

Shipping, storage and sampling

How is the lipid shipped, and how should I store it?
Ships from Shanghai. Storage: 2 years -20°C Powder, 2 weeks 4°C in DMSO, 6 months -80°C in DMSO
Pure lipid or solution — which should I choose?
Pure lipid is generally more stable during shipping and storage, so we usually recommend the pure form. A solution in ethanol or chloroform can be supplied when required by your workflow. Tell us the intended application, solvent and target concentration so the most suitable format can be confirmed.
