Fig. 5From: Development and validation of a PCR-free nucleic acid testing method for RNA viruses based on linear molecular beacon probesResults of fluorescence signals on RNA virus probes in live-cells were compared with qRT-PCR analysis. A Changes of fluorescence intensity of CSFV on cells. B The results of CSFV E2 gene qRT-PCR were compared with it. C Changes of fluorescence intensity of SARS-CoV-2-N on cells. D The results of SARS-CoV-2Â N gene qRT-PCR were compared with itBack to article page
