Sulfo-Cyanine7 is a fluorescent dye commonly used in biological research and medical imaging applications. It belongs to the cyanine dye family and is characterized by its near-infrared (NIR) emission wavelength, which ranges from 750 to 800 nanometers. This makes sulfo-Cyanine7 particularly useful for in vivo imaging, as it can penetrate deeply into tissue and provide high-resolution images with minimal background interference.
Sulfo-Cyanine7 is often conjugated to biomolecules such as antibodies, peptides, and proteins, allowing for specific targeting and imaging of cells and tissues of interest. Its high quantum yield and photostability also make it ideal for long-term imaging experiments.
