Description

1,2-Distearoyl-Sn-Glycero-3-Phosphoglycerol, Sodium Salt is a high-purity, synthetic phospholipid derivative, specifically a sodium salt of phosphatidylglycerol (PG) with saturated stearoyl chains. This compound is a critical functional component in the formulation of advanced lipid-based delivery systems and biomimetic membranes. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors who require precise control over lipid composition for applications ranging from drug delivery to model membrane studies.

Application

• Liposome & Nanoparticle Formulation: A key phospholipid component for creating stable, anionic liposomes used in drug and gene delivery systems.
• Biomimetic Membrane Research: Used to construct model cell membranes (e.g., supported lipid bilayers, vesicles) for studying membrane-protein interactions and biophysical properties.
• Pulmonary Surfactant Mimetics: Serves as a critical ingredient in synthetic lung surfactant formulations for research and therapeutic development.
• Diagnostic Reagents: Employed in the development of lipid-based reagents for diagnostic assays and imaging.
• Cosmetic & Dermal Delivery: Functions as a high-performance emulsifier and penetration enhancer in premium cosmetic and transdermal products.
• Cell Culture & Cryopreservation: Used as an additive in specialized cell culture media and cryoprotectant formulations.
