Patent

CA 2503890

In one aspect, the invention relates to the use of RNA-replicases for introducing mutations into and selecting for improved RNA molecules. The present invention also relates to the use of ribavirin, or a derivative/analogue thereof, in methods for introducing one or more mutations during replication or transcription of a target nucleic acid molecule. These methods can be used to screen for nucleic acids, or proteins encoded thereby, with altered or new activity. The present invention also provides kits comprising ribavirin, or a derivative/analogue thereof, for use in mutagenesis procedures.

Cette invention concerne, dans une variante, l'utilisation d'ARN-réplicases pour introduire des mutations dans des molécules d'ARN améliorées et les sélectionner. Cette invention concerne également l'utilisation de la ribavirine, ou d'un dérivé/analogue de celle-ci, dans des méthodes consistant à introduire une ou plusieurs mutations pendant la réplication ou la transcription d'une molécule d'acide nucléique cible. Ces méthodes peuvent servir au criblage d'acides nucléiques ou de protéines codées par ces derniers, présentant une activité nouvelle ou modifiée. Cette invention concerne enfin des nécessaires contenant de la ribavirine ou un dérivé/analogue de celle-ci utilisés dans les procédés de mutagénèse.
