Thymidine-5'-triphosphate trisodium salt is widely used in molecular biology and biochemistry research. It serves as a crucial substrate in DNA synthesis and sequencing processes, particularly in polymerase chain reaction (PCR) and enzymatic DNA labeling. This compound is essential for studying DNA replication mechanisms and for the incorporation of thymidine into DNA strands during in vitro experiments. Additionally, it is utilized in the development of diagnostic assays and in the production of labeled nucleotides for various analytical techniques, such as fluorescence-based detection methods. Its role in supporting enzymatic reactions makes it a key component in genetic engineering and biotechnology applications.
