Abstract
L'invention concerne des procédés d'atténuation du biais de méthylation pendant la préparation de bibliothèques de séquençage. Les procédés peuvent comprendre, par exemple, l'extraction de fragments d'ADN d'un échantillon ; la réalisation d'au moins l'un des éléments suivants : (i) une première réaction de réparation d'extrémité, la première réaction de réparation d'extrémité comprenant l'utilisation d'une ADN polymérase sans déplacement de brin ; ou (ii) une seconde réaction de réparation d'extrémité, la seconde réaction de réparation d'extrémité comprenant l'utilisation d'un mécanisme de terminaison de chaîne ; la réalisation d'au moins l'un parmi : (iii) une réaction de queue destinée à ajouter un brin polynucléotidique en extension aux fragments d'ADN réparés en bout, la réaction de queue comprenant l'utilisation d'un seul désoxynucléotide triphosphate (dNTP) ; ou (iv) une réaction de réparation de césure/espacement à l'aide d'une ADN ligase pour remplir des césures ou des espacements simple brin dans les fragments d'ADN réparés en bout, pour générer une pluralité de fragments d'ADN modifiés ; et effectuer une analyse de méthylation de molécules d'acide nucléique dérivées de la pluralité de fragments d'ADN modifiés.
