Description

1-Stearoyl-2-Arachidonylphosphatidylcholine is a defined, high-purity phospholipid species, a critical component for advanced biochemical and pharmaceutical research. This compound is essential for studying membrane biophysics, lipid signaling pathways, and the role of specific phospholipids in cellular function. It is particularly valuable for researchers and manufacturers in lipidomics, drug delivery systems (liposomes), and as a standard in analytical chemistry.

Application

• Lipidomics Research & Biomarker Discovery: Used as a pure standard for the identification and quantification of phospholipids in complex biological samples via mass spectrometry.
• Liposome & Drug Delivery System Formulation: A key structural lipid for creating defined, stable liposomal carriers for targeted drug and gene delivery.
• Biochemical & Cell Biology Studies: Essential for investigating the specific roles of phosphatidylcholine species in cell membrane dynamics, signal transduction (e.g., via arachidonic acid release), and apoptosis.
• Pharmaceutical Reference Standard: Serves as a certified reference material (CRM) for quality control and assay development in pharmaceutical laboratories.
• Model Membrane Systems: Used to create synthetic lipid bilayers (e.g., vesicles, supported lipid bilayers) with precise composition for biophysical studies.
• Nutritional & Cosmetic Research: Investigated for its potential role in specialized nutraceutical formulations and advanced cosmetic delivery systems.
