1,2-Dipalmitoyl-sn-glycero-3-phospho-L-serine, sodium salt by Molecular Depot is a sodium salt of 1,2-dipalmitoyl-sn-glycero-3-phospho-L-serine (DPPS), a saturated anionic phospholipid. Phosphatidylserine is normally confined to the inner leaflet of the plasma membrane, and its appearance on the outside is the signal that marks an apoptotic cell for clearance. It is used as an anionic component in liposome formulation, in annexin V and apoptosis assay development and in membrane research. Each unit contains 5 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
