NHS-dPEG®13-DSPE, product number 10028 (PN10028), is designed for use in liposomes and micelles. This product replaces product number 11029, TFP-dPEG®13-DSPE. The lipophilic end of the molecule is the lipid 1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (DSPE) modified by conjugation to a single molecular weight, discrete polyethylene glycol (dPEG®) chain that is 43 atoms (54.8 – 55.8 Å) long with a mass of 657 Daltons. The dPEG® spacer is functionalized as an N-hydroxysuccinimide (NHS) ester. The NHS ester reacts with primary or secondary amines to form amide bonds, allowing for surface modification of a liposome or micelle with peptides, proteins, or small molecule drugs.
