Cellules compétentes
Les cellules compétentes sont celles dont les parois cellulaires ont été modifiées afin de faciliter l’incorporation d’ADN étranger dans leur intérieur. Les cellules sont rendues compétentes par un processus utilisant le chlorure de calcium et un choc thermique, et les cellules en croissance très rapide deviennent compétentes plus facilement que celles à d’autres stades de croissance. Des facteurs tels que l’efficacité de transformation, les marqueurs génétiques et les formats de conditionnement influenceront le temps et l’effort requis pour votre projet, ainsi que son succès. Choisissez parmi plusieurs types et formats cellulaires afin d’assurer une fonction optimale.
