Patent number: 10900038Abstract: Modification formats having modified nucleotides are provided for siRNA. Short interfering RNA having modification formats and modified nucleotides provided herein reduce off-target effects in RNA interference of endogenous genes. Further modification formatted siRNAs are demonstrated to be stabilized to nuclease-rich environments.
