Comparison between MLV pseudotype neutralization and the Siemens SARS-CoV-2 IgG assay. Siemens SARS-CoV-2 IgG assay measuring IgG binding to recombinant receptor binding domain (horizontal axis) was compared by linear regression to the MLV pseudotype assay (vertical axis). Samples used in this experiment were #8 (shown in Fig. 2) and #13 and #15–18, not used in previous figures
