Pseudovirus neutralization assay. Antibodies: SARS-CoV-2 (COVID-19) Spike RBD Antibodies, orb1274179 (E10). Luciferase reporter virus-like particles and 293T-hsACE2 cells were used for the assay. After 72 hrs incubation infectivity was measured by luciferase expression using Promega Renilla-Glo Luciferase Assay System. Infectivity was measured as RLUs and no sdAb control was set to 100% infectivity. Neutralization activity of orb1274179 (E10) was measured over a serial dilution to determine the half-maximal inhibitory concentration (IC50). orb1274179 (E10) exhibited a dose dependent neutralizing effect on all the variant pseudoviruses tested.
ACE2-RBD binding inhibitory ELISA. Antibodies: SARS-CoV-2 (COVID-19) Spike RBD Antibodies, orb1274179. ACE2-RBD binding inhibitory ELISA was performed using RBD protein of SARS-CoV-2 variants (wild-type, alpha, beta, epsilon, gamma and kappa) as coating antigens at 1 µg/mL and the anti-SARS-CoV-2 (COVID-19) RBD antibody orb1274179 as the capture antibody, followed by incubation with 20 ng/mL human ACE2-Fc. Bound h-ACE2-Fc was detected with a goat anti-human IgG-HRP conjugate (1:20000 dilution) using the TMB chromogenic substrate system. orb1274179 exhibited a dose dependent inhibitory effect on ACE2 binding to RBDs of all the variants tested.
ELISA Validation with RBDs of SARS-CoV-2 Variants. Antibodies: SARS-CoV-2 (COVID-19) Spike RBD Antibody, orb1274179. A direct ELISA was performed using RBD protein of SARS-CoV-2 variants (wild-type, alpha, beta, gamma and Delta) as coating antigens at 1 µg/mL and the anti-SARS-CoV-2 (COVID-19) RBD antibody (orb1274180) as the capture antibody, followed by anti-cMyc-tag antibody (orb1239964) at 1 µg/mL. Secondary: Goat anti-mouse IgG HRP conjugate at 1:5000 dilution. orb1274180 binds to RBDs of all the variants tested.
Pseudovirus neutralization assay. Antibodies: SARS-CoV-2 (COVID-19) Spike RBD Antibodies, orb1274180 (A10) and orb1274179 (E10). Luciferase reporter virus-like particles and 293T-hsACE2 cells were used for the assay. After 72 hrs incubation infectivity was measured by luciferase expression using Promega Renilla-Glo Luciferase Assay System. Infectivity was measured as RLUs and no sdAb control was set to 100% infectivity. Neutralization activity of orb1274180 (A10) and orb1274179 (E10) was measured over a serial dilution series to determine the half-maximal inhibitory concentration (IC50). Both orb1274180 (A10) and orb1274179 (E10) exhibited a dose dependent neutralizing effect on wild-type pseudoviruses, and the combination of the two showed a significantly synergistic effect.
