Abstract
Seroconversion to SARS-CoV-2 has been widely studied to evaluate infection spreading for epidemiological purpose, or even in studies of protective immunity in convalescent or vaccinated individuals. The viral particle has an envelope harboring the spike glycoprotein, which can be used as an antigen for assay development, to detect antiviral antibodies to SARS-CoV-2. Since several vaccines encode a spike subunit, the full length spike-based immunoassay should be a universal tool to evaluate seroconversion. In this manuscript, we propose a low-cost ELISA that can be used to detect antiviral IgG to SARS-CoV-2 in human serum.

Results from Barzooka: We found bar graphs of continuous data. We recommend replacing bar graphs with more informative graphics, as many different datasets can lead to the same bar graph. The actual data may suggest different conclusions from the summary statistics. For more information, please see Weissgerber et al (2015).
Results from JetFighter: We did not find any issues relating to colormaps.
