DSPE-PEG-PDP是一种能与游离巯基反应的活性磷脂PEG衍生物。DSPE（1,2-二硬脂酰-sn-甘油-3-磷酸乙醇胺）是一种高度疏水的18碳磷脂。另一方面，PEG主链具有良好的亲水性和水溶性。PDP（吡啶基二硫化物）功能化的DSPE-PEG能够与游离巯基反应形成二硫键，可被DTT或其他二硫键还原试剂切割。PDP和硫醇之间的反应允许DSPE-PEG高效地附着到含硫醇的分子或颗粒上。

Phospholipids PEG hydrophobic base pyridine (DSPE - PEG - OPSS) can be used to modify proteins, peptides and other materials with reactive group. Phospholipids (- DSPE) conjugate polyethylene glycol (peg) is a phospholipids and polyethylene glycol (peg) combined with hydrophilic and hydrophobic. PEG modification can improve the solubility and stability, reduce the immunogenicity of protein and peptide. It can also inhibit non-specific combination of charged molecules on the surface modification.
