Description

Sulfo Cy7 Amine is a near-infrared (NIR) fluorescent dye derivative functionalized with a reactive amine group and sulfonate moieties for enhanced water solubility. This compound is essential for creating bright, stable, and biocompatible fluorescent conjugates for advanced detection and imaging applications. It is primarily utilized by researchers and manufacturers in the biotechnology, pharmaceutical, and diagnostic sectors for labeling biomolecules such as antibodies, proteins, and oligonucleotides.

Application

• Biomolecule Labeling: Conjugation to antibodies, proteins, peptides, and oligonucleotides for fluorescence-based assays (e.g., ELISA, Western Blot, flow cytometry).
• In Vivo Imaging: Synthesis of NIR probes for deep-tissue optical imaging in preclinical animal studies due to minimal tissue autofluorescence and absorption.
• Diagnostic Reagents: Development of fluorescent detection kits and biosensors for clinical diagnostics and point-of-care testing.
• Cell Tracking and Staining: Labeling of cells for migration, proliferation, and cytotoxicity studies in cell-based research.
• Material Science: Incorporation into polymers or nanoparticles to create functional fluorescent materials for sensing and tracking applications.
• Drug Delivery Research: Tagging of drug carriers, liposomes, or nanoparticles to monitor biodistribution and pharmacokinetics.
