Uridine,2′-deoxy-5-etynyl- CAS:61135-33-9

5-ethynyl-2′-deoxyuridine (EdU) wani nau'in nucleoside ne wanda ake amfani da shi a fannin ilmin kwayoyin halitta da binciken ilmin kwayoyin halitta. Ana amfani da shi akai-akai don yiwa lakabi da gano sabbin DNA da aka haɗa a cikin ƙwayoyin halitta masu rai ta hanyar wani tsari da aka sani da "click chemistry." Wannan dabarar tana ba da damar gani da ƙididdige kwafi na DNA da yaduwar ƙwayoyin halitta. EdU ya zama madadin da aka fi so ga bromodeoxyuridine analog na gargajiya na thymidine (BrdU) saboda dacewarsa da na'urar hangen nesa ta fluorescence da rashin matakan denaturation na DNA masu tsauri yayin ganowa. Bugu da ƙari, tsarin sinadarai na EdU yana ba da damar gano takamaiman kuma mai inganci, wanda hakan ya sa ya zama kayan aiki mai mahimmanci don nazarin haɗakar DNA da yanayin zagayowar ƙwayoyin halitta.
