Phospholipid polyethylene glycol folate (dspe-peg-fa), carboxyl group and amino group form amide bond. This reaction makes folate ligand attach to protein, antibody, peptide or particle surface. Pegylated folate has good water solubility and bioactivity. Folate functionalized substrates have been used for targeted drug delivery, imaging and bioassay. DSPE (1,2-distearyl-sn-glycerin-3-phosphate ethanolamine) is a saturated 18 carbon phospholipid, which is 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.
It was dried at - 20 ℃ and kept away from light for 12 months to avoid frequent dissolution and freeze-drying.
