Title
(EN) NUCLEIC ACID-GUIDED NUCLEASE OR NICKASE FUSION EDITING OF METHYLATED NUCLEOTIDES
(FR) NUCLÉASE GUIDÉE PAR UN ACIDE NUCLÉIQUE DE L'ÉDITION PAR FUSION DE NICKASE DE NUCLÉOTIDES MÉTHYLÉS
Abstract
(EN) The present disclosure relates to compositions, methods, modules and automated, integrated instrumentation to enable nucleic acid-guided nuclease or nickase fusion editing in cells and correlating the edits to the resulting cellular nucleic acid profile. In some embodiments, methylated bases in a repair template are substituted for unmethylated bases in the cellular target genome and in some embodiments, unmethylated bases are substituted for methylated bases in the cellular target genome.
(FR) La présente invention concerne des compositions, des procédés, des modules et une instrumentation intégrée automatisée pour permettre l'édition de nucléase guidée par acide nucléique ou de fusion de nickase dans des cellules et la corrélation des éditions au profil d'acide nucléique cellulaire obtenu. Dans certains modes de réalisation, des bases méthylées dans un modèle de réparation sont substituées pour des bases non méthylées dans le génome cible cellulaire et, dans certains modes de réalisation, des bases non méthylées sont substituées pour des bases méthylées dans le génome cible cellulaire.
