摘要
The 10DM24 deoxyribozyme can site-specifically label RNAs with fluorophore-GTP conjugates; however, the 2 ',5 '-branched RNA linkage is readily cleaved by debranchase. To prevent loss of labels upon cleavage, we synthesized phosphorothioate-modified, fluorescent GTP derivatives and elaborated conditions for their incorporation by 10DM24. RNAs labeled with fluorescent derivatives of Sp-GTP(S) were found to be resistant to debranchase.
