Anti-SARS-CoV-2 RBD Potent Neutralizing Antibody, Chimeric mAb, Human IgG1 (AM128) on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Immobilized SARS-CoV-2 S protein RBD, His Tag (Cat. No. SPD-C52H3) at 1 μg/mL (100 μL/well) can bind Anti-SARS-CoV-2 RBD Potent Neutralizing Antibody, Chimeric mAb, Human IgG1 (AM128) (Cat. No. SPD-M128) with a linear range of 0.05-0.78 ng/mL (QC tested).
Serial dilutions of Anti-SARS-CoV-2 RBD Potent Neutralizing Antibody, Chimeric mAb, Human IgG1 (AM128) (Cat. No. SPD-M128) was detected by SARS-CoV-2 Inhibitor screening Kit (Cat. No. EP-105) with a half maximal inhibitory concentration (IC50) of 1.197 μg/mL (Routinely tested).
Serial dilutions of Anti-SARS-CoV-2 RBD Potent Neutralizing Antibody (Cat. No. SPD-M128) was incubated with SARS-CoV-2 pseudotyped virus at 37 ℃ for 1 hour. Afterward, Huh-7 cells were added, followed by incubation at 37 ℃ for 24h. Chemiluminescence detection was performed and the virus neutralization titers (IC50) is 0.03255 nM using the Reed-Muench method.
Loaded Anti-SARS-CoV-2 RBD Potent Neutralizing Antibody, Chimeric mAb, Human IgG1 (AM128) (Cat. No. SPD-M128) on AHC Biosensor, can bind SARS-CoV-2 S1 protein, His Tag (Cat. No. S1N-C52H4) with an affinity constant of 4.42 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
