Fig. 4From: Differential gene expression analysis of common target genes for the detection of SARS-CoV-2 using real time-PCRComparison of the cycle threshold (∆Ct) value of SARS-COV-2 expression. A HPRT gene was used as an internal control. A significant difference is indicated by *P < 0.05. ****, Ns = Not significant (0.611). B RP gene was used as an internal control. A significant difference is indicated by *P < 0.05. ****, Ns = Not significant, (0.608).Back to article page
