The present invention relates to an improvement in a method for amplifying a target sequence of a target polynucleotide. The method comprises combining a sample suspected of containing the target polynucleotide with reagents for amplifying the target sequence and subjecting the combination to conditions wherein the target sequence if present is amplified. The present improvement comprises including in the combination a control oligonucleotide and a control polynucleotide that has a sequence that is hybridizable with the control oligonucleotide. When the control oligonucleotide is bound to the control polynucleotide, the ability of a primer to chain extend along the control polynucleotide is reduced. Optionally, the control oligonucleotide is part of the control polynucleotide. The method finds particular application in the area of nucleic acid amplification and detection.

La présente invention concerne une amélioration apportée à un procédé pour amplifier une séquence cible d'un polynucléotide cible. Le procédé consiste à combiner un échantillon suspecté de contenir le polynucléotide cible avec des réactifs pour amplifier la séquence cible et à soumettre cette combinaison à des conditions dans lesquelles la séquence cible, lorsqu'elle est présente, est amplifiée. L'amélioration consiste à inclure dans la combinaison un oligonucléotide témoin et un polynucléotide témoin comportant une séquence qui peut être hybridée à l'oligonucléotide témoin. Lorsque l'oligonucléotide témoin est lié au polynucléotide témoin, la capacité d'une amorce à s'étendre en chaîne le long du polynucléotide témoin est réduite. De manière facultative, l'oligonucléotide témoin fait partie du polynucléotide témoin. Le procédé trouve des applications particulières dans le domaine de l'amplification et de la détection d'acide nucléique.
