Molecular imaging is revolutionizing our understanding of biological systems and disease progression. At its core are highly specific and sensitive imaging agents, with near-infrared (NIR) fluorescent dyes like Cyanine5.5 Carboxylic Acid (CY5.5-COOH) playing an increasingly vital role. For professionals in pharmaceuticals, biotechnology, and academic research, understanding the applications and effective sourcing of CY5.5-COOH is key to advancing their work.

CY5.5-COOH is a cyanine dye renowned for its strong absorption and emission in the NIR region (typically around 675/694 nm). This spectral profile is advantageous for in vivo imaging, as NIR light penetrates biological tissues more effectively than visible light, minimizing autofluorescence and scattering. Researchers utilize CY5.5-COOH to develop targeted contrast agents for various imaging modalities, facilitating early disease detection and monitoring treatment efficacy.

The carboxylic acid group on CY5.5-COOH provides a convenient handle for conjugation. This allows the dye to be covalently linked to targeting ligands, such as antibodies or peptides, creating sophisticated molecular probes that can selectively bind to specific cells or tissues. This precision is crucial for applications like cancer imaging, where identifying tumor margins accurately is essential.

For R&D teams and procurement specialists, sourcing high-quality CY5.5-COOH is paramount.
