Fig. 4: RCA with rapid electrochemical detection of N and S genes of SARS-CoV-2 in clinical samples.
From: Rapid electrochemical detection of coronavirus SARS-CoV-2
a The detection of N gene in 51 RNA samples. b The detection of S gene in 51 RNA samples. c The detection of N gene in 55 cDNA samples. d The detection of S gene in 55 cDNA samples. All samples used for the evaluation were prepared from nasopharyngeal swabs. The current signals from electrochemical measurements of the N gene (blue bar graph) and S gene (orange bar graph) are shown compared with the Cq result from qRT-PCR (blue dots for N gene and orange dots for S gene. All current responses are presented as mean values±standard deviation (SD), n = 5, whereas Cq values are from single measurements).
