DMG-PEG2000-NHS is a PEG derivative that can be used in various biomedical applications, such as the construction of drug delivery systems (siRNA delivery liposomes, lipid nanoparticle, etc.). The active ester (NHS) can react with an amino group (-NH2) to form a stable amide bond, which can be used as a linker in a bioconjugation strategy to modify amino-linked peptide proteins as well as other small molecules.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
