Abstract[English]
The present disclosure relates to methods, compositions and kits for synthesizing moderate length RNAs (mlRNAs, including gRNAs) by splint-mediated ligation of RNA fragments. The synthesis of moderate length RNAs can be followed by DNase treatment. In some embodiments, splint DNA oligonucleotides that are no longer than 32 nucleotides are used.[French]
La présente divulgation concerne des procédés, des compositions et des kits pour synthétiser des ARN de longueur modérée (ARNm, y compris les ARNg) par ligature de fragments d'ARN par "attelle" (splint). La synthèse d'ARN de longueur modérée peut être suivie d'un traitement à la DNase. Dans certains modes de réalisation, on utilise des oligonucléotides d'ADN splint ne dépassant pas 32 nucléotides.
