Description

1,2-Distearoyl-Sn-Glycero-3-Phosphatidyl-Rac-Glycerol, Sodium Salt is a synthetic, saturated phospholipid, specifically a phosphatidylglycerol (PG) derivative. This high-purity lipid is critical for constructing stable, biomimetic membrane systems and advanced drug delivery vehicles. It is essential for researchers and manufacturers in pharmaceutical development, liposome formulation, and biophysical research requiring precise membrane composition and functionality.

Application

• Liposome & Lipid Nanoparticle (LNP) Formulation: A key structural component for creating stable, anionic liposomal bilayers used in drug and vaccine delivery systems.
• Biomimetic Membrane Models: Used in research to create synthetic membranes that mimic bacterial or mitochondrial membranes for studying protein-lipid interactions.
• Pulmonary Surfactant Research: Serves as a synthetic analog in studies related to lung surfactant composition and function.
• Drug Encapsulation: Enhances the loading efficiency and stability of encapsulated therapeutic agents, particularly for sustained-release applications.
• Cell Culture & Transfection Reagents: A component in specialized lipid mixtures used for cell membrane studies and non-viral gene delivery.
• Analytical Standards: Used as a high-purity reference standard in chromatographic analysis (HPLC, LC-MS) for lipidomics research.
