Thymidine (CAT: R014550) is a naturally occurring nucleoside composed of the pyrimidine base thymine linked to deoxyribose. As one of the four essential DNA building blocks, it plays a central role in DNA replication, repair, and cell proliferation. In research, Thymidine is widely used in cell cycle studies, particularly for synchronization at the S-phase, and in investigations of nucleotide metabolism. It also serves as a precursor in radiolabeled or modified nucleosides for molecular imaging, antiviral research, and genetic studies. With broad applications across cancer biology, virology, and molecular genetics, Thymidine remains a fundamental reagent in biomedical research.
