Biochem/physiol Actions

DNA labeled with 5-chloro-2′-deoxyuridine (CldU) serves as an effective tool to analyze and quantify DNA replication, repair, and recombination. CldU is a potent mutagen, clastogen, and toxicant. It is used as a thymidine analog and is found to alter the dNTP pools and might lead to cell-cycle arrest. CldU produces sister-chromatid exchange but has less response to ionizing radiation compared to other thymine analogs. 5-Chloro-2′-deoxyuridine (CldU) is used to study the miscoding potential of hypochlorous acid damage to DNA and DNA precursors. When used with antibody based immunofluorescent imaging, 5-Chloro-2′-deoxyuridine incorporation may be used in protocols to identify sites of DNA replication. CldU may be used as a labeling substrate in conjunction with other halogenated uridine labeling substrates such as iododeoxyuridine (IdU).
