SARS-CoV-2 proteome microarray for global profiling of COVID-19 specific IgG and IgM responses

Abstract: We still know very little about how the human immune system responds to SARS-CoV-2. Here we construct a SARS-CoV-2 proteome microarray containing 18 out of the 28 predicted proteins and apply it to the characterization of the IgG and IgM antibodies responses in the sera from 29 convalescent patients. We find that all these patients had IgG and IgM antibodies that specifically bind SARS-CoV-2 proteins, particularly the N protein and S1 protein. Besides these proteins, significant antibody responses to ORF9b and… Show more

“…54,77 We speculate that the reason why more antibodies are developed to the S protein is because the S protein is on the SAR-CoV-2 surface and is more easily recognized by the immune system. 80,85 2) Standardization of sample collection. The specimen and collection time from infected patient may have great influence on the detection result.…”

“…A number of studies have begun to unravel the antibody response to SARS-CoV-2 beyond a simple "yes or no" answer [9][10][11][12][13][14][15][16][17][18] . Here, we hypothesized that by examining the antibody profile in patient's serum in terms of antigens, antibody isotypes (IgG, IgM, and IgA), and neutralization, we would be able to identify specific signatures associated to effective SARS-CoV-2 neutralization.…”

“…Other SARS-CoV-2 proteins such as ORF9b (accessory protein 9b) and NSP5 (non-structural protein 5) also demonstrate significant antibody responses. This SARS-CoV-2 proteome microarray provides antibody profiling capabilities that support new diagnostic, treatment, and vaccination research efforts; 107 however, it includes 18/28 of the proteins encoded in the genome of SARS-CoV-2, 90 none of which were prepared using mammalian cells, potentially affecting the antibody–antigen interactions. Moreover, only 29 clinical samples were tested and, as such, increasing the number of samples and diversifying the time point of specimen collection can further reveal the dynamics of antibody profiling.…”
