What Are Fluorescent Phospholipids?
Fluorescent phospholipids are lipid molecules covalently or structurally modified with fluorophores to enable visualization and quantitative analysis of membrane structure, lipid trafficking, and lipid-based delivery systems. By integrating fluorophores into phospholipid headgroups or acyl chains, these probes allow precise tracking of lipid distribution without significantly altering bilayer properties. Fluorescent phospholipids are widely used in liposome formulation, lipid nanoparticle development, membrane fusion studies, endocytosis research, and in vivo imaging of lipid-mediated transport processes.

General Workflow for Fluorescent Phospholipid Services
Project Assessment & Strategy Design
We assess your target phospholipid class (e.g., PC, PE, PS, PG, cardiolipin), intended use (liposome/LNP formulation, membrane biophysics, cellular trafficking, or in vivo studies), and preferred imaging platform. Based on these inputs, we recommend fluorophore families and labeling positions (headgroup, acyl chain, or PEG-linked) to balance detectability with membrane fidelity.
Sample Preparation & Pre-Processing
We confirm lipid identity and starting material format (powder or solution), review solvent compatibility, and define handling conditions to reduce oxidation and hydrolysis. If you provide a lipid blend or formulation target, we align specifications (molar ratios, PEG content, charge lipids) to ensure the fluorescent phospholipid integrates as intended.
Fluorescent Phospholipid Labeling / Synthesis
Fluorescent phospholipids are prepared using lipid-appropriate modification strategies selected for the lipid class and fluorophore chemistry. We control labeling position and dye loading to minimize self-quenching and avoid disrupting bilayer behavior, supporting reproducible performance in liposomes, LNPs, and model membranes.
Purification & Removal of Free Dye / Byproducts
Products are purified to remove unreacted dye and side products using lipid-suitable purification workflows (e.g., chromatographic or preparative methods appropriate for hydrophobic amphiphiles). The goal is high-purity fluorescent phospholipid material that performs consistently when incorporated into lipid bilayers and formulated particles.
Quality Control & Data Verification
Each fluorescent phospholipid is verified for identity and purity by analytical methods standard to lipid chemistry (e.g., LC-MS and chromatographic purity checks) and characterized for fluorescence performance (excitation/emission profile). Where needed, we can review incorporation behavior in representative lipid systems to support formulation development.
Final Delivery & Technical Support
You receive the fluorescent phospholipid with documentation for handling and storage (light protection, temperature guidance) and practical suggestions for incorporation into liposomes or LNPs (mole percent ranges and mixing considerations). Our technical team supports follow-up questions on imaging setup, assay design, and troubleshooting to help ensure reliable downstream results.
