Description

L-α-Phosphatidylethanolamine (Liver, Bovine) is a high-purity, naturally sourced phospholipid extracted from bovine liver tissue. This compound serves as a critical structural and functional component of biological membranes and is a key precursor in lipid metabolism research. It is essential for B2B clients in the pharmaceutical, nutraceutical, and advanced life science research sectors requiring authentic, biologically relevant lipid standards and raw materials for formulation development.

Application

• Pharmaceutical Excipient & Drug Delivery: As a key component in liposomal and nanoparticle formulations for targeted drug delivery systems.
• Biochemical Research & Diagnostics: Used as a standard or substrate in enzymatic assays, membrane biophysics studies, and lipidomics research.
• Cell Culture & Media Supplement: Employed to supplement serum-free media to support cell growth and membrane integrity in specialized bioprocessing.
• Nutraceutical & Cosmetic Formulations: Incorporated into high-end supplements and cosmetic products for its purported cell membrane-supporting and emulsifying properties.
• Model Membrane Systems: Essential for constructing artificial lipid bilayers and vesicles (e.g., liposomes) used to study membrane protein function and permeability.

Quality Control

Our L-α-Phosphatidylethanolamine (Liver, Bovine) is produced and handled under strict quality management protocols. Each batch is analyzed to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by HPLC), fatty acid profile, and oxidation indices are provided. We adhere to cGMP principles where applicable to support our clients in regulated markets.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation. Allow the product to reach room temperature in a desiccator before opening to prevent moisture condensation. Keep away from strong oxidizers.
