Applications:

DMG-PEG 2000 is used for the preparation of liposomes for siRNA delivery, which can improve delivery efficiency. DMG-PEG 2000 can also be used in the preparation of lipid nanoparticles for in vivo delivery of oral plasmid DNA. DMG-PEG 2000 can improve the mucus permeability and delivery efficiency of nanoparticles.

Packaging:

1g/bag, 5g/bag, 10g/bag, 20g/bag, 50g/bag or 100g/bag.

Recommended Storage Conditions:
Kept at -20±5℃ under an inert atmosphere.
To reduce the moisture absorption, it should be slowly warmed to ambient temperature before opened.

Shelf Life:
24 months if stored under above conditions.
