Product Information

Description	DSPE-PEG-COOH sodium salt is the sodium form of carboxylated DSPE-PEG, offering enhanced chemical stability and straightforward reactivity for covalent coupling. The carboxyl terminus enables reliable activation for peptide or protein conjugation, while the PEG segment maintains colloidal stability and prevents aggregation. This compound integrates seamlessly into lipid membranes, forming a versatile platform for surface functionalization, ligand attachment, and biomolecule immobilization. DSPE-PEG-COOH sodium salt is extensively utilized in the preparation of targeted liposomes, bioconjugate materials, and PEGylated lipid systems optimized for reproducible research and formulation development.
