Product overview

Description & Application

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.

Handling guidance

Shipping, storage and sampling

How is the lipid shipped, and how should I store it?
Ships from Shanghai. Storage: 2 years -20°C Powder, 2 weeks 4°C in DMSO, 6 months -80°C in DMSO
Pure lipid or solution — which should I choose?
Pure lipid is generally more stable during shipping and storage, so we usually recommend the pure form. A solution in ethanol or chloroform can be supplied when required by your workflow. Tell us the intended application, solvent and target concentration so the most suitable format can be confirmed.
