    Indirect ELISA showing primary antibody ab273073 (CR3022, human chimeric) binding to the antigens ab272105 (recombinant human coronavirus SARS-CoV-2 Spike Glycoprotein S1 (sheep Fc fusion)) and ab273068 (recombinant human coronavirus SARS-CoV-2 Spike Glycoprotein S1 (Active)). Plates were coated with 100ng/well ab272105 or ab273068 and binding of ab273073 assessed in serial dilution from 200ng/ml primary antibody in duplicate. Binding was detected using ab98624, an anti-human Fc secondary conjugated to HRP. Data are represented as the mean and error bars represent standard deviation.
