PEG(2000)-C-DMG represents a PEGylated derivative synthesized from 1,2-dimyristoyl-sn-glycerol (1,2-DMG). This compound is instrumental in the formulation of lipid nanoparticles (LNPs), particularly when combined with other lipidic compounds, for the efficient delivery of small interfering RNA (siRNA). Specifically, LNPs incorporating PEG(2000)-C-DMG and encapsulating siRNA designed to target the genes responsible for encoding programmed cell death protein ligand 1 (PD-L1) and PD-L2 have demonstrated efficacy in reducing the expression levels of PD-L1 and PD-L2 in monocyte-derived dendritic cells. Furthermore, formulations that include PEG(2000)-C-DMG are being actively explored in the advancement of LNPs aimed at the delivery of siRNA-based vaccines, highlighting its critical role in the development of therapeutic and prophylactic strategies.

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.
