ELISA results of Mouse Anti-SARS CoV-2 Spike Protein (S2) Antibody using orb348651. Each well was coated in duplicate with 0.5 µg of rec SARS CoV-2 Whole Spike protein [RED line], rec SARS CoV-2 Spike (S1) [GREEN line], rec SARS CoV-2 Spike (S1) RBD protein [BLUE line], and rec SARS CoV-2 Spike (S2) glycoprotein [PURPLE line]. The working dilution for SARS-CoV-2 whole spike is 1:190000 and SARS CoV-2 Spike (S2) glycoprotein is 1:120000. The starting dilution of antibody was 0.55 µg/ml and the X-axis represents the Log10 of a 3-fold dilution. This titration is a 4-parameter curve fit where the IC50 is defined as the titer of the antibody. Assay performed using Rabbit Anti-Mouse IgG HRP conjugated (p/n orb347506) at 1:8000 and TMB substrate (p/n orb348651). SARS CoV-2 Spike (S2) EC50: 8 ng/mL; SARS CoV-2 Whole Spike EC50: 5 ng/mL.
