Description

Bodipy 581/591 C11 CAS NO 217075-36-0 is a highly specialized, lipophilic fluorescent dye belonging to the boron-dipyrromethene (BODIPY) family, functionalized with a long alkyl chain. This compound is engineered for superior performance in membrane biology research, offering exceptional photostability and a large Stokes shift to minimize spectral overlap. It is an essential tool for researchers and industrial scientists in life sciences, pharmaceutical development, and material science who require precise, reliable fluorescent probes for lipid bilayer labeling, membrane fluidity studies, and cellular imaging.

Application

• Lipid Membrane and Vesicle Labeling: Selective staining of liposomes, lipid droplets, and cellular membranes for fluorescence microscopy and flow cytometry.
• Membrane Fluidity and Dynamics Studies: Used as an environment-sensitive probe to monitor phase transitions, lipid packing, and microdomain formation in model and biological membranes.
• Live-Cell Imaging: Long-term tracking of membrane structures and processes in live cells due to its excellent photostability and low cytotoxicity.
• Fluorescence Resonance Energy Transfer (FRET): Serves as an efficient donor or acceptor pair in FRET-based assays for studying molecular interactions at membrane interfaces.
• High-Throughput Screening (HTS): Development of cell-based assays in drug discovery to identify compounds that affect membrane properties or lipid metabolism.
• Material Science Research: Investigation of polymer films, nanoparticles, and other advanced materials where hydrophobic fluorophore incorporation is needed.
