Product overview

Description & Application

Polyethylene glycol phospholipid is an excellent material to form liposomes, which can be used for gene transfection, vaccine delivery, drug transportation, and targeted drug delivery. Phospholipids are hydrophobic and hydrophilic. It can be used to modify protein drugs, peptide compounds, organic small molecule drugs, biological materials, etc. Cy7 labeled PEG derivatives are used for fluorescence tracing or fluorescence observation.

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.
