Indirect ELISA showing ab277513 (CV30) binding to purified His-tagged SARS-CoV2-RBD. Plates were coated with 100ng/well purified protein and binding of ab277513 assessed in serial dilution from 100ng/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.

Indirect ELISA showing ab277513 (CV30) binding to ab272105 (recombinant human coronavirus SARS-CoV-2 Spike Glycoprotein S1 (sheep Fc fusion)). Plates were coated with 100ng/well ab272105 and binding of ab277513 assessed in serial dilution from 100ng/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.

Indirect competition ELISA showing competitive binding of ab277513 (CV30) to purified Fc-tagged SARS-CoV2-RBD in the presence of 2nM His-tagged human ACE2. Plates were coated with 100ng/well SARS-CoV2-RBD and binding of the recombinant ACE2 determined in duplicate in the presence of a serial dilution (from 330nM) of primary antibody. His-tagged ACE2 binding was detected using ab1187, an anti-His tag secondary conjugated to HRP. Data are represented as the mean and error bars represent standard deviation.
