1,2-Dioleoyl-sn-glycero-3-phospho-L-serine sodium (Cat No.:I045260) is an anionic phospholipid composed of a glycerol backbone esterified with two oleic acid chains and linked to a phospho-L-serine headgroup, presented as its sodium salt. DOPS is a key component of cell membranes, particularly in the inner leaflet of the plasma membrane, where it contributes to membrane fluidity, curvature, and signaling. It plays roles in apoptosis, coagulation, and protein–membrane interactions. In research, DOPS is used in liposome formulation, membrane biophysics studies, and drug delivery systems to model or manipulate phosphatidylserine-mediated cellular processes and lipid–protein interactions.
