All samples had been classified as SARS-CoV-2-positive by three reverse-transcription and quantitative polymerase chain reaction (RT-qPCR) analyses identifying E-, S-, and N-gene RNAs. For protein precipitation, 1 mL of acetone (−20°C) was added to 750 μL of gargle solution and stored overnight at −20°C. We present a protein MS-based method to specifically detect SARS-CoV-2 virus proteins from highly diluted gargle solutions of COVID-19 patients. Using this approach, we were able to identify peptides originating from SARS-CoV-2 nucleoprotein in gargle solution samples. ./cache/cord-326581-31trqhi1.txt ./txt/cord-326581-31trqhi1.txt
