Cy3-UTP sodium salt is a modified form of uridine triphosphate (UTP) with a Cyanine 3 (Cy3) fluorescent dye attached to the 5th position of the uracil base. This modification allows for the labeling of RNA molecules during transcription, enabling their visualization in biological assays. The sodium salt addition enhances solubility and stability, making it useful in molecular biology applications such as RNA labeling, fluorescence in situ hybridization (FISH), and real-time RNA detection, aiding research in gene expression and RNA biology.
