Cy3-CTP Sodium Salt is a derivative of cytidine triphosphate (CTP) with a Cy3 fluorophore attached to the 5-position of the pyrimidine ring. Cy3 is a cyanine dye commonly used as a fluorescent label in molecular biology applications such as fluorescence in situ hybridization (FISH), microarray analysis, and RNA labeling. The sodium salt form enhances its solubility and stability, making it suitable for enzymatic reactions involving RNA synthesis or modification, where fluorescently labeled nucleotides are required for visualization or detection purposes.
