Description

1-Palmitoyl-2-Parinaroylphosphatidylcholine is a synthetic, fluorescently-labeled phospholipid, specifically a phosphatidylcholine with a parinaroyl fatty acid chain. This compound is a critical tool for advanced biophysical and biochemical research, enabling the study of membrane dynamics, lipid-protein interactions, and vesicle fusion. It is primarily utilized by research institutions, pharmaceutical R&D departments, and diagnostic developers working in membrane biophysics, lipidomics, and fluorescence-based assay development.

Application

• Membrane Biophysics Research: As a fluorescent probe to study lipid bilayer properties, phase transitions, and membrane fluidity.
• Lipid-Protein Interaction Studies: To investigate the binding and activity of membrane-associated proteins, enzymes, and peptides.
• Liposome & Model Membrane Formation: A key component in creating fluorescently-tagged liposomes for drug delivery research and membrane fusion assays.
• Fluorescence Spectroscopy & Microscopy: Used in Förster resonance energy transfer (FRET) experiments and fluorescence quenching studies to measure molecular distances and interactions.
• Biochemical Assay Development: Serves as a substrate or tracer in enzymatic assays for phospholipases and other lipid-modifying enzymes.
• Cell Biology: For labeling and tracking cellular membranes in vitro without disrupting native membrane architecture.

Quality Control

Every batch of our high-purity 1-Palmitoyl-2-Parinaroylphosphatidylcholine is manufactured and analyzed under strict quality protocols. We ensure compliance with rigorous internal standards suitable for research applications. Comprehensive analytical data, including purity by HPLC and confirmation of structure, is documented in a Certificate of Analysis (COA) provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation and hydrolysis. The product is hygroscopic (moisture-sensitive) and light-sensitive; allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation.
