At indicated times, samples were removed from the heating block and cooled on ice to stop the reaction. Photographs were taken using the color scanner function of an office copy machine and show the red to yellow color change in positive samples. (B) The RT-LAMP reaction product (2.5 μl) was analyzed on a 2% agarose gel. The typical band pattern of a successful RT-LAMP reaction was visible in the samples with 100 or more SARS-CoV-2 RNA molecules, i.e., in those samples that showed a color change from red to yellow after 30 min.","divisions":[{"label":"label","span":{"begin":0,"end":6}},{"label":"title","span":{"begin":8,"end":66}}],"tracks":[{"project":"LitCovid-PD-FMA-UBERON","denotations":[{"id":"T62","span":{"begin":62,"end":65},"obj":"Body_part"},{"id":"T63","span":{"begin":117,"end":130},"obj":"Body_part"},{"id":"T64","span":{"begin":117,"end":120},"obj":"Body_part"},{"id":"T65","span":{"begin":151,"end":155},"obj":"Body_part"},{"id":"T66","span":{"begin":650,"end":663},"obj":"Body_part"},{"id":"T67","span":{"begin":650,"end":653},"obj":"Body_part"}],"attributes":[{"id":"A62","pred":"fma_id","subj":"T62","obj":"http://purl.org/sig/ont/fma/fma67095"},{"id":"A63","pred":"fma_id","subj":"T63","obj":"http://purl.org/sig/ont/fma/fma84126"},{"id":"A64","pred":"fma_id","subj":"T64","obj":"http://purl.org/sig/ont/fma/fma67095"},{"id":"A65","pred":"fma_id","subj":"T65","obj":"http://purl.org/sig/ont/fma/fma74402"},{"id":"A66","pred":"fma_id","subj":"T66","obj":"http://purl.org/sig/ont/fma/fma84126"},{"id":"A67","pred":"fma_id","subj":"T67","obj":"http://purl.org/sig/ont/fma/fma67095"},{"subj":"T62","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T63","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T64","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T65","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T66","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T67","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T48","span":{"begin":138,"end":146},"obj":"Disease"},{"id":"T49","span":{"begin":639,"end":647},"obj":"Disease"}],"attributes":[{"id":"A48","pred":"mondo_id","subj":"T48","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A49","pred":"mondo_id","subj":"T49","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"subj":"T48","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T49","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T104","span":{"begin":68,"end":69},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T105","span":{"begin":151,"end":155},"obj":"http://purl.obolibrary.org/obo/OGG_0000000002"},{"id":"T106","span":{"begin":462,"end":463},"obj":"http://purl.obolibrary.org/obo/CLO_0001021"},{"id":"T107","span":{"begin":519,"end":522},"obj":"http://purl.obolibrary.org/obo/CLO_0001562"},{"id":"T108","span":{"begin":519,"end":522},"obj":"http://purl.obolibrary.org/obo/CLO_0001563"},{"id":"T109","span":{"begin":565,"end":566},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T110","span":{"begin":700,"end":701},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"}],"attributes":[{"subj":"T104","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T105","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T106","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T107","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T108","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T109","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T110","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-CHEBI","denotations":[{"id":"T40","span":{"begin":121,"end":130},"obj":"Chemical"},{"id":"T41","span":{"begin":524,"end":531},"obj":"Chemical"},{"id":"T42","span":{"begin":654,"end":663},"obj":"Chemical"}],"attributes":[{"id":"A40","pred":"chebi_id","subj":"T40","obj":"http://purl.obolibrary.org/obo/CHEBI_25367"},{"id":"A41","pred":"chebi_id","subj":"T41","obj":"http://purl.obolibrary.org/obo/CHEBI_2511"},{"id":"A42","pred":"chebi_id","subj":"T42","obj":"http://purl.obolibrary.org/obo/CHEBI_25367"},{"subj":"T40","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T41","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T42","pred":"source","obj":"LitCovid-PD-CHEBI"}]},{"project":"LitCovid-PubTator","denotations":[{"id":"151","span":{"begin":149,"end":150},"obj":"Gene"},{"id":"152","span":{"begin":138,"end":148},"obj":"Species"},{"id":"153","span":{"begin":639,"end":649},"obj":"Species"},{"id":"154","span":{"begin":292,"end":295},"obj":"Chemical"},{"id":"155","span":{"begin":524,"end":531},"obj":"Chemical"}],"attributes":[{"id":"A151","pred":"tao:has_database_id","subj":"151","obj":"Gene:43740575"},{"id":"A152","pred":"tao:has_database_id","subj":"152","obj":"Tax:2697049"},{"id":"A153","pred":"tao:has_database_id","subj":"153","obj":"Tax:2697049"},{"id":"A154","pred":"tao:has_database_id","subj":"154","obj":"MESH:D007053"},{"id":"A155","pred":"tao:has_database_id","subj":"155","obj":"MESH:D012685"},{"subj":"151","pred":"source","obj":"LitCovid-PubTator"},{"subj":"152","pred":"source","obj":"LitCovid-PubTator"},{"subj":"153","pred":"source","obj":"LitCovid-PubTator"},{"subj":"154","pred":"source","obj":"LitCovid-PubTator"},{"subj":"155","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/"},{"pre
