5-Ethynyl-2′-deoxyuridine (EdU) CAS:61135-33-9 is a chemical compound that contains several functional groups, including an ethynyl group and a deoxyribose sugar. EdU is a thymidine analog that is incorporated into newly synthesized DNA during cell division, which makes it a valuable tool for detecting cell proliferation and DNA synthesis.
The ethynyl group in EdU is particularly useful, as it can react with azide groups in the presence of a copper catalyst to form a covalent bond, which can be used to label and visualize cells that are actively synthesizing DNA. This process, known as “click chemistry”, allows researchers to monitor cell proliferation and differentiation in real-time, providing insights into the mechanisms of cellular growth and development.
