Zusammenfassung:The present invention in general provides a method for amplification of a target RNA, comprising the steps of (i) transfering a liquid with a first volume comprising at least one or more living cells into a vessel (ii) adding to said vessel an RT-PCR reaction buffer with a second volume, whereas said second volume is at least 2x as large as said first volume (iii) lysing said at least one or more living cells within said vessel by means of incubation for at least 20 seconds at at least 90°C, and (iv) amplifying said target by means of a one-step RT-PCR without performance of an intermediate purification step. La présente invention concerne en général un procédé d'amplification d'un ARN cible, comprenant les étapes de (i) transfert dans un récipient d'un liquide ayant un premier volume comprenant au moins une ou plusieurs cellules vivantes, (ii) ajout audit récipient d'un tampon de réaction de RT-PCR ayant un second volume, ledit second volume étant au moins 2x plus grand que ledit premier volume, (iii) lyse de ladite ou desdites cellules vivantes à l'intérieur dudit récipient au moyen d'une incubation pendant au moins 20 secondes à au moins 90°C et (iv) amplification de ladite cible au moyen d'une RT-PCR à étape unique sans mise en oeuvre d'une étape de purification intermédiaire.
