Product Name:DSPE-PEG-Amine
English Name:DSPE-PEG-Amine
CAS No.:474922-26-4
Aliases:DSPE-PEG-NH2, 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-polyethylene glycol-amine
Physical Properties:This product is an amphiphilic polymer composed of hydrophobic distearoyl phosphatidylethanolamine, hydrophilic polyethylene glycol, and terminal amino groups. It appears as a white to off-white solid or viscous liquid. It is soluble in organic solvents such as DMSO, DMF, and chloroform, and can self-assemble into micelles or liposomes in water. Store at low temperature, dry and protected from light.
Uses:As a functional PEG derivative, it is used for PEGylation of proteins, peptides, and drug molecules to improve stability and reduce immunogenicity. The phospholipid moiety enables its use in preparing liposomal drug delivery systems for targeted delivery and long circulation.
Technical Specifications:
Purity: ≥95%
Substitution rate: DSPE ≥95%, NH2 ≥95%
Appearance: viscous liquid or solid powder
Solubility: soluble in DMSO, DMF and other organic solvents
Storage: store frozen under inert gas protection, avoid moisture absorption and deactivation
