Cy5.5

Description:
Cy5.5, or Cyanine 5.5, is a near-infrared fluorescent dye commonly used in biological imaging and labeling applications. It is characterized by its strong fluorescence properties, particularly in the near-infrared region, which allows for deep tissue penetration and reduced background fluorescence in biological samples. The dye exhibits high molar absorptivity and quantum yield, making it suitable for sensitive detection methods such as fluorescence microscopy and flow cytometry. Cy5.5 is typically used in conjugation with biomolecules, such as antibodies or nucleic acids, to facilitate the visualization of specific targets in complex biological systems. Its stability under various conditions, including light and pH variations, enhances its utility in long-term experiments. Additionally, Cy5.5 is compatible with other fluorescent dyes, enabling multiplexing in imaging studies. Overall, its unique optical properties and versatility make Cy5.5 a valuable tool in the fields of molecular biology and medical diagnostics.
