SUNBRIGHT GS-020EX is an extremely high-purity PEG lipid (commonly known as DSG-PEG2000) designed to enhance the stability and efficiency of lipid nanoparticle (LNP) drug delivery systems. It features two C18:0 fatty acids (stearic acid) connected at the 1- and 2-positions of a glycerol backbone, and a polyethylene glycol (PEG) chain of 2,000 Da linked at the 3-position. By incorporating polyethylene glycol (PEG) into the surface of LNPs, it improves the stability and circulation time of LNPs in the bloodstream, facilitating efficient delivery of encapsulated therapeutic agents such as mRNA, siRNA, and other nucleic acids. GS-020EX is a key component in LNP formulations to improve the delivery and performance of nucleic acid-based therapies.
