Cy5-UTP sodium salt is a modified form of uridine triphosphate (UTP) with a Cyanine 5 (Cy5) fluorescent dye attached to the 5th position of the uracil base. This modification enables the labeling of RNA molecules during transcription, allowing for their visualization and detection in various biological assays. The addition of a sodium salt enhances the compound's solubility and stability, making it suitable for applications in molecular biology and biochemistry. Cy5-UTP sodium salt is commonly used in RNA labeling techniques, fluorescence in situ hybridization (FISH) assays, real-time monitoring of RNA synthesis and degradation pathways, and the visualization of RNA localization within cells. This compound serves as a valuable tool for studying gene expression, RNA trafficking, and other RNA-related processes in biological systems, contributing significantly to our understanding of cellular function and regulation.
