Fluorescein-12-UTP, with the CAS number 134367-01-4, is a modified nucleotide that incorporates fluorescein, a fluorescent dye, into the structure of uridine triphosphate (UTP). This compound is characterized by its ability to emit fluorescence upon excitation, making it a valuable tool in various biochemical and molecular biology applications, particularly in labeling and detecting RNA. The fluorescein moiety provides a bright green fluorescence, which can be easily visualized using fluorescence microscopy or flow cytometry. Fluorescein-12-UTP is often used in in vitro transcription assays, where it serves as a substrate for RNA polymerases, allowing researchers to track the synthesis of RNA molecules. Its stability and solubility in aqueous solutions enhance its utility in experimental protocols. Additionally, the incorporation of fluorescein into RNA can facilitate the study of RNA dynamics, localization, and interactions within cellular environments. Overall, fluorescein-12-UTP is a versatile reagent that combines the properties of nucleotides with the advantages of fluorescent labeling.
