Description

n-(Lissamine-Rhodamine B Sulfonyl)-1,2-Dipalmitoylphosphatidylethanolamine is a high-purity, fluorescently labeled phospholipid derivative, essential for advanced biophysical and cell biology research. This compound provides a critical tool for membrane modeling, vesicle tracking, and cellular imaging due to its bright, stable fluorescence when incorporated into lipid bilayers. It is primarily required by researchers and manufacturers in the pharmaceutical, diagnostic, and life science sectors for developing targeted drug delivery systems and high-sensitivity assays.

Application

• Liposome & Vesicle Labeling: Fluorescent tagging of model membranes for tracking and stability studies.
• Cellular Membrane Imaging: Visualization of membrane dynamics, fusion, and trafficking in live-cell microscopy.
• Drug Delivery Research: Incorporation into targeted liposomal formulations to study biodistribution and cellular uptake.
• Biophysical Assays: Use in fluorescence resonance energy transfer (FRET) and fluorescence correlation spectroscopy (FCS) experiments.
• Diagnostic Kit Development: Component in high-sensitivity lateral flow or immunoassay platforms requiring fluorescent signal generation.
• Biomimetic Membrane Studies: Fabrication of supported lipid bilayers (SLBs) for sensor development and interaction analysis.
