  • Method for fragmenting double-stranded RNA and use of the same
    Patent number: 10894981
    Abstract: The object is to provide a method that enables detection of unknown virus sequences and efficient detection and search of viruses. The method comprises the step of randomly fragmenting an objective double-stranded (ds) RNA to obtain dsRNA fragments; the step of subjecting the obtained dsRNA fragments to a reverse transcription reaction and then performing polymerase chain reaction (PCR) to obtain corresponding DNA fragments; and the step of subjecting the obtained DNA fragments to a sequence analysis operation to determine the sequences. The reverse transcription reaction is preferably started from the 3? ends of the dsRNA fragments.
    Type: Grant
