Product Description: Distearoylphosphatidylserine sodium is an anionic phospholipid with stearic acid tails (18:0) and contains a carboxylic acid (COOH) and amine (NH2) in their head group. It has been used in the preparation of lipid-mixing vesicles, liposome, or artificial membrane. Due to the medium size of fatty acid chain, DLPS is used to form thinner membranes/walls.
