Description

Dipentyl-3,3,3',3'-Tetramethylindocarbocyanine is a near-infrared (NIR) fluorescent dye belonging to the cyanine family, characterized by its pentyl-substituted indole rings. This compound matters for its excellent photostability and high molar extinction coefficient, making it a superior choice for demanding fluorescence-based detection and imaging applications. It is primarily needed by researchers and manufacturers in the fields of bioconjugation, flow cytometry, and in vivo imaging, where deep tissue penetration and low background signal are critical.

Application

• Fluorescent Labeling and Bioconjugation: Used to tag antibodies, proteins, peptides, and nucleic acids for sensitive detection assays.
• In Vivo and Deep-Tissue Imaging: Ideal for non-invasive optical imaging in animal models due to its near-infrared emission, minimizing tissue autofluorescence.
• Flow Cytometry and Cell Sorting: Serves as a bright, photostable fluorophore for cell surface marker analysis and high-throughput screening.
• Optical Sensor Development: Incorporated into chemical sensors and probes for detecting ions, small molecules, or changes in the microenvironment.
• Materials Science Research: Applied in the development of advanced materials like organic light-emitting diodes (OLEDs) and nonlinear optical (NLO) materials.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer agent in therapeutic applications.
