2'-O-MOE-U
Based on 1 Customer Validation
2'-O-MOE-U is a nucleic acid modification group (Phosphoramidite) with 3'-exonuclease inhibitory activity. 2'-O-MOE-U also exhibits gene silencing activity and double-stranded oligonucleotide stability. By forming steric interactions with 3'-exonuclease residues, 2'-O-MOE-U anchors the 3'-end of the siRNA guide strand in the hAgo2 PAZ domain, thereby regulating double-stranded thermal stability and enhancing base-pairing specificity. 2'-O-MOE-U does not induce IFNα production, can be incorporated at multiple sites of siRNA to enhance RNAi activity, and produces a synergistic effect with 2'-F modification. 2'-O-MOE-U has been widely used in studies related to breast cancer and other diseases.

Biological Activity
2′-O-MOE-U (35 mU/mL SVPD; up to 180 min) modification increases the stability of dT10-mer oligonucleotides against 3′-exonuclease (SVPD), with ON7 exhibiting a T1/2 of ~22 min[1].
2'-O-MOE-U modification increases the serum stability of 14-mer single-stranded DNA, with a half-life of 206.9 min in 10% FBS, compared to 33.4 min for unmodified DNA[2].
2'-O-MOE-U (0.5 nM) reduces off-target effects while exhibiting approximately 60% targeted gene silencing at 0.5 nM in lipofected cells[3].
