Product overview

Description & Application

DSPE-PEG2000-NHS is a reactive PEGylated phospholipid for liposome surface modification and bioconjugation research. It combines a DSPE lipid anchor, a PEG segment and a terminal NHS ester for attachment to amine-containing molecules.

Handling guidance

Shipping, storage and sampling

How is the lipid shipped, and how should I store it?
Ships from Shanghai. Pure form: −20 °C, 1 year. In solvent: −80 °C, 6 months; −20 °C, 1 month. Sealed and protected from light and moisture.
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.
