产品描述
5-Ethynyl-2'-deoxyuridine (EdU) is a nucleoside analog of thymidine that is used to monitor de novo DNA synthesis through click chemistry.It is an alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs.
体外活性
PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].Like 5-bromo-2’-deoxyuridine (BrdU), EdU is incorporated into DNA during active DNA synthesis. It can then be detected using a fluorescent azide probe and copper catalysis using 1,3-dipolar cycloaddition.Modified nucleosides, including EdU, can be cytotoxic when added to cells for prolonged periods[2].5-Ethynyl-2'-deoxyuridine (EdU) staining is a fast, sensitive and reproducible method to study cell proliferation in the central nervous system[3]
