Zwei nicht radioaktive Methoden wurden für die Ermittlung des artichoke mottled crinkle Tombusvirus (AMCV) in Artischockenpflanzensaft angewandt. In der ersten Methode wurde eine Sandwich-Hybrjdisierungsmethode entwickelt, die einen mit Biotin versehenen Transkriptor als Empfänger und eine dioxigeninmarkierte Riboprobe anwendet. Die Hybride wurde an Nylonmembranen, die mit Streptavidin beschichtet worden waren, nach einem Dot-Blot Verfahren gesammclt. Die zweite Methode war die Reverse Transcriptional Polymerase. Chain Reaktion (RT-PCR), die mit drei verschiedenen, weit auseinander befindlichen Sequenzen des AMCV-Genoms Primer durchgeführt wurde. Im Artischockenpflanzensaft war RT-PCR 20-Each empfindhcher als die Sandwich-Hybridisierung und 2,5-fach weniger empfindlich als Dot-Blot-Hybridisierung mit radioaktivmarkierten Referentgruppen.

A sandwich hybridization method was developed using a biotinylated transcript as capture and a digoxigenin-labelled riboprobe.

The second method was the reverse transcriptional polymerase chain reaction (RT-PCR) carried out with three different primers obtained from widely, separated sequences of AMCV genome.

Abstract
Two non-radioactive methods were applied for the detection of artichoke mottled crinkle tombusvirus (AMCV) in artichoke plant sap. A sandwich hybridization method was developed using a biotinylated transcript as capture and a digoxigenin-labelled riboprobe. The hybrid was collected onto Nylon membranes coated with streptavidin using a slot-blot procedure. The second method was the reverse transcriptional polymerase chain reaction (RT-PCR) carried out with three different primers obtained from widely, separated sequences of AMCV genome. In artichoke plant sap, RT-PCR was 20-fold more sensitive than sandwich-hybridization and 2.5-fold less sensitive than dor-blot hybridization labelled with radioactive reporter groups.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
