5-Ethynyl-2'-deoxyuridine [CAS: 61135-33-9]

5-Ethynyl-2′-deoxyuridine (EdU) is a nucleoside analog of thymidine used to monitor DNA synthesis and cell proliferation. Incorporated into replicating DNA, it allows sensitive detection via click chemistry with fluorescent azides, enabling quantitative analysis of cell proliferation, cytotoxicity, and cell cycle studies in mammalian and microbial systems. Ideal for research in molecular biology, cancer studies, and drug screening.
