From: A SISCAPA-based approach for detection of SARS-CoV-2 viral antigens from clinical samples
Detection of SARS-CoV-2 viral antigens from clinical samples using SISCAPA workflow. A 41 nasopharyngeal swab samples that were positive for SARS-CoV-2 using RT-PCR testing were processed using the workflow described in this study. The cumulative peak areas for all the three peptides are plotted against the Ct values reported by the RT-PCR testing. B Box plots of peak areas for each peptide are plotted across different groups based on the Ct values (Ct values < 20, 20–22, 22–26 and > 26) of the SARS-CoV-2 positive samples as indicated
