Real-time RT-PCR\nThe optimal concentration of primers and probes, which were synthesized using a published sequence [12], was determined with the RNA transcripts of SARS-CoV. The primer and probe sequences used for RNA-dependent RNA polymerase gene detection were: 5′-GTGARATGGTCATGTGTGGCGG-3′ (Forward), 5′-CARATGTTAAASACACTATTAGCATA-3′ (Reverse) and 5′-CAGGTGGAACCTCATCAGGAGATGC-3′ (Probe in 5-FAM/3′-BHQ format) and the primer and probe sequences used for E gene detection were: 5′-ACAGGTACGTTAATAGTTAATAGCGT-3′ (Forward), 5′-ATATTGCAGCAGTACGCACACA-3′ (Reverse) and 5′-ACACTAGCCATCCTTACTGCGCTTCG-3′ (Probe in 5-FAM/3′-BHQ format). A 25-μL reaction was setup that contained 5 μL of RNA, 12.5 μL of 2 × reaction buffer provided with the Agpath IDTM 1 step RT-PCR system (Thermo Fisher Scientific, Waltham, USA), 1 μL of 25 × enzyme mixture, 1 μL of forward and reverse primers at 10 pM, and 0.5 μL of each probe at 10 pM. Reverse transcription was performed at 50°C for 30 minutes, followed by inactivation of the reverse transcriptase at 95°C for 10 minutes. PCR amplification was performed with 40 cycles at 95°C for 15 seconds and 60°C for 1 minute using an ABI 7500 Fast instrument (Thermo Fisher Scientific).","divisions":[{"label":"title","span":{"begin":0,"end":19}}],"tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"119","span":{"begin":168,"end":176},"obj":"Species"}],"attributes":[{"id":"A119","pred":"tao:has_database_id","subj":"119","obj":"Tax:694009"},{"subj":"119","pred":"source","obj":"LitCovid-PubTator"}],"namespaces":[{"prefix":"Tax","uri":"https://www.ncbi.nlm.nih.gov/taxonomy/"},{"prefix":"MESH","uri":"https://id.nlm.nih.gov/mesh/"},{"prefix":"Gene","uri":"https://www.ncbi.nlm.nih.gov/gene/"},{"prefix":"CVCL","uri":"https://web.expasy.org/cellosaurus/CVCL_"}]},{"project":"LitCovid-PD-FMA-UBERON","denotations":[{"id":"T17","span":{"begin":149,"end":152},"obj":"Body_part"},{"id":"T18","span":{"begin":218,"end":221},"obj":"Body_part"},{"id":"T19","span":{"begin":232,"end":235},"obj":"Body_part"},{"id":"T20","span":{"begin":247,"end":251},"obj":"Body_part"},{"id":"T21","span":{"begin":464,"end":468},"obj":"Body_part"},{"id":"T22","span":{"begin":687,"end":690},"obj":"Body_part"}],"attributes":[{"id":"A17","pred":"fma_id","subj":"T17","obj":"http://purl.org/sig/ont/fma/fma67095"},{"id":"A18","pred":"fma_id","subj":"T18","obj":"http://purl.org/sig/ont/fma/fma67095"},{"id":"A19","pred":"fma_id","subj":"T19","obj":"http://purl.org/sig/ont/fma/fma67095"},{"id":"A20","pred":"fma_id","subj":"T20","obj":"http://purl.org/sig/ont/fma/fma74402"},{"id":"A21","pred":"fma_id","subj":"T21","obj":"http://purl.org/sig/ont/fma/fma74402"},{"id":"A22","pred":"fma_id","subj":"T22","obj":"http://purl.org/sig/ont/fma/fma67095"},{"subj":"T17","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T18","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T19","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T20","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T21","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T22","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T25","span":{"begin":168,"end":176},"obj":"Disease"}],"attributes":[{"id":"A25","pred":"mondo_id","subj":"T25","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"subj":"T25","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T35","span":{"begin":98,"end":99},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T36","span":{"begin":247,"end":251},"obj":"http://purl.obolibrary.org/obo/OGG_0000000002"},{"id":"T37","span":{"begin":464,"end":468},"obj":"http://purl.obolibrary.org/obo/OGG_0000000002"},{"id":"T38","span":{"begin":637,"end":638},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T39","span":{"begin":1179,"end":1189},"obj":"http://purl.obolibrary.org/obo/OBI_0000968"}],"attributes":[{"subj":"T35","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T36","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T37","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T38","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T39","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-CHEBI","denotations":[{"id":"T9","span":{"begin":193,"end":198},"obj":"Chemical"},{"id":"T10","span":{"begin":397,"end":402},"obj":"Chemical"},{"id":"T11","span":{"begin":437,"end":442},"obj":"Chemical"},{"id":"T12","span":{"begin":615,"end":620},"obj":"Chemical"},{"id":"T13","span":{"begin":716,"end":722},"obj":"Chemical"},{"id":"T14","span":{"begin":836,"end":843},"obj":"Chemical"},{"id":"T15","span":{"begin":910,"end":915},"obj":"Chemical"}],"attributes":[{"id":"A9","pred":"chebi_id","subj":"T9","obj":"http://purl.obolibrary.org/obo/CHEBI_50406"},{"id":"A10","pred":"chebi_id","subj":"T10","obj":"http://purl.obolibrary.org/obo/CHEBI_51617"},{"id":"A11","pred":"chebi_id","subj":"T11","obj":"http://purl.obolibrary.org/obo/CHEBI_50406"},{"id":"A12","pred":"chebi_id","subj":"T12","obj":"http://purl.obolibrary.org/obo/CHEBI_51617"},{"id":"A13","pred":"chebi_id","subj":"T13","obj":"http://purl.obolibrary.org/obo/CHEBI_35225"},{"id":"A14","pred":"chebi_id","subj":"T14","obj":"http://purl.obolibrary.org/obo/CHEBI_60004"},{"id":"A15","pred":"chebi_id","subj":"T15","obj":"http://purl.obolibrary.org/obo/CHEBI_50406"},{"subj":"T9","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T10","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T11","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T12","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T13","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T14","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T15","pred":"source","obj":"LitCovid-PD-CHEBI"}]},{"project":"LitCovid-PD-GO-BP","denotations":[{"id":"T4","span":{"begin":926,"end":947},"obj":"http://purl.obolibrary.org/obo/GO_0001171"},{"id":"T5","span":{"begin":934,"end":947},"obj":"http://purl.obolibrary.org/obo/GO_0006351"},{"id":"T6","span":{"begin":1026,"end":1039},"obj":"http://purl.obolibrary.org/obo/GO_0003968"},{"id":"T7","span":{"begin":1026,"end":1039},"obj":"http://purl.obolibrary.org/obo/GO_0003899"}
