Description

1,2-Dipalmitoyl-Sn-Glycero-3-Phospho-L-Serine (Monosodium Salt) is a high-purity, synthetic phospholipid derivative, specifically a phosphatidylserine (PS) species. This compound is a critical building block for constructing biomimetic membranes and liposomal drug delivery systems, offering superior batch-to-batch consistency for research and formulation. It is essential for pharmaceutical developers, academic researchers, and manufacturers in the advanced drug delivery, diagnostic, and cosmetic industries who require reliable, well-characterized lipid excipients.

Application

• Liposomal Drug Delivery Systems: A key component for creating anionic, stealth, or targeted liposomes to enhance drug solubility, stability, and cellular uptake.
• Biomimetic Membrane Research: Used in model membrane studies (e.g., vesicles, supported lipid bilayers) to investigate cell signaling, protein-lipid interactions, and membrane biophysics.
• Pharmaceutical Formulations: Serves as a functional excipient in injectable and topical formulations where membrane fusion or specific charge characteristics are required.
• Diagnostic Reagents: Employed in the development of diagnostic assays and imaging agents that rely on lipid-based nanoparticles.
• Cosmetic Actives: Incorporated into high-end skincare products for its purported role in supporting skin barrier function and cellular membrane health.
• Biochemical Research: A standard reagent for studying apoptosis, blood coagulation, and other serine-phospholipid-mediated cellular processes.
