Description

1,1'-Dioctadecyl-3,3,3',3'-Tetramethylindocarbocyanine Perchlorate is a high-purity, long-chain dialkyl carbocyanine dye salt, widely recognized as a vital fluorescent membrane probe. Its core value lies in its exceptional ability to integrate into lipid bilayers, providing stable and intense fluorescence for labeling and tracking cellular membranes. This product is essential for researchers and industrial developers in life sciences, particularly for applications in biophysics, cell biology, and diagnostic assay development.

Application

• Fluorescent Cell Membrane Labeling: Used extensively as a lipophilic tracer for staining and visualizing plasma membranes, organelles, and lipid vesicles in live and fixed cells.
• Lipid Bilayer and Vesicle Studies: Critical for probing membrane fluidity, fusion, trafficking, and model membrane (liposome) characterization in biophysical research.
• Flow Cytometry and Fluorescence Microscopy: Serves as a key fluorescent dye for cell sorting (FACS) and high-resolution imaging techniques due to its bright emission and photostability.
• Neuronal Tracing: Employed in neurobiology for anterograde and retrograde labeling of neuronal pathways.
• Diagnostic Assay Development: Utilized in the formulation of fluorescent probes and kits for diagnostic applications and high-throughput screening (HTS).
• Material Science Research: Applied in the development of advanced fluorescent nanomaterials and sensors.
