Detection of SARS-CoV-2 serum antibodies in critical COVID-19 patients. a Workflow of the longitudinal analyses of SARS-CoV-2 proteome antibodies in the serum of critical COVID-19 patients. b Characteristics of the COVID-19 patients in this study. c The reproducibility of serological antibody detection using the SARS-CoV-2 proteome microarray within an experiment and between different experiments. The r correlation was calculated within an array and between different arrays. d Representative fluorescent image of antibody detection using serum from a COVID-19 patient who did not survive at different days post symptom onset
