In this study, we report the development of RT-PCR assays to detect this novel virus in human clinical specimens. Two monoplex real-time RT-PCR assays targeting the ORF1b and N gene regions of 2019-nCoV were designed based on the first publicly available sequence in Genbank (Accession number: MN908947). Viral RNA from cells infected by SARS coronavirus or DNA plasmids containing the target sequences were positive in the assays as expected. In addition, the N gene RT-PCR assay was found to be more sensitive in detecting 2019-nCoV RNA in the studied clinical samples. ./cache/cord-261279-6mef38eo.txt ./txt/cord-261279-6mef38eo.txt
