ʻUridine,2′-deoxy-5-ethynyl-CAS:61135-33-9

ʻO 5-ethynyl-2′-deoxyuridine (EdU) kahi analog nucleoside i hoʻohana nui ʻia ma ke kahua o ka biology molecular a me ka noiʻi biology cell. Hoʻohana pinepine ʻia ia e lepili a ʻike i ka DNA i hoʻohui hou ʻia i loko o nā cell ola ma o kahi kaʻina hana i ʻike ʻia ʻo "click chemistry." ʻAe kēia ʻenehana no ka nānā ʻana a me ka helu ʻana o ka hana hou ʻana o ka DNA a me ka hoʻonui ʻana o nā cell. Ua lilo ʻo EdU i mea koho kaulana i ka thymidine analog bromodeoxyuridine (BrdU) kuʻuna ma muli o kona kūlike me ka microscopy fluorescence a me ka ʻole o nā ʻanuʻu denaturation DNA koʻikoʻi i ka wā o ka ʻike ʻana. Eia kekahi, ʻae ka ʻano kemika o EdU no ka ʻike kikoʻī a me ka maikaʻi, e lilo ia i mea hana waiwai no ke aʻo ʻana i ka synthesis DNA a me ka dynamics o ke kaʻina hana cell.
