Abstract

L'invention, qui a trait à des molécules d'ARN isolées, dotées d'une affinité élevée pour des acides aminés particuliers, porte également sur des procédés permettant d'isoler ces molécules ainsi que sur leur utilisation. On isole ces molécules d'ARN par le biais d'une technique faisant intervenir différentes étapes de lavage et de réchauffage.
