Sulfo-Cyanine5 dimethyl is a highly versatile and water-soluble fluorescent dye, well-suited for a wide range of pharmaceutical research and development applications. This dye features a sulfo-functionalized variant of the Cyanine5 (Cy5) chromophore, characterized by its distinctive red-shifted fluorescence emission in the far-red region of the visible spectrum.
The introduction of the sulfonate (-SO3-) functional groups enhances the dye’s water solubility and reduces aggregation, thus improving its performance in various biological environments. In addition, the dimethyl (CH3)2 modification further contributes to the increased hydrophilicity and stability of the dye, making it an ideal candidate for numerous bioconjugation techniques.
Sulfo-Cyanine5 dimethyl is widely utilized in pharmaceutical R&D due to its excellent photostability and minimal cytotoxicity. Applications include fluorescence microscopy, flow cytometry, in vivo imaging, and Förster resonance energy transfer (FRET) studies. The dye’s compatibility with a broad range of biomolecules, such as proteins, nucleic acids, and nanoparticles, facilitates its use in the investigation of molecular interactions, drug delivery systems, and disease diagnostics.
