Anti-SARS-CoV-2 Spike RBD Antibody, Chimeric mAb, Human IgG1 (AM122) on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
The purity of Anti-SARS-CoV-2 Spike RBD Antibody, Chimeric mAb, Human IgG1 (AM122)(Cat. No. S1N-M12A1) is more than 90% and the molecular weight of this protein is around 135-150 kDa verified by SEC-MALS.
Immobilized SARS-CoV-2 S1 protein, His Tag (Cat. No. S1N-C52H2) at 2 μg/mL (100 μL/well) can bind Anti-SARS-CoV-2 Spike RBD Antibody, Chimeric mAb, Human IgG1 (AM122) (Cat. No. S1N-M12A1) with a linear range of 0.08-2.5 ng/mL (QC tested).
Detection SARS-CoV-2 S protein RBD by Sandwich ELISA Assay.
Immobilized Anti-SARS-CoV-2 Spike S1 Antibody, chimeric mAb (Cat. No. S1N-M12A1) at 2 μg/mL (100 μL/well) can bind S protein RBD. And then add Anti-SARS-CoV-2 Spike S1 Antibody (Cat. No. S1N-M13A1) (Biotinylated in house) at 1:5000. Detection was performed using HRP-conjugated streptavidin with sensitivity of 25 pg/mL (Routinely tested).
Anti-SARS-CoV-2 Spike RBD Neutralizing antibody (Cat.No. S1N-M12A1) neutralizes SARS-CoV-2 Spike RBD by inhibiting RBD: ACE2 interaction. The ACE2-coated plate is incubated with the wild type (WT) RBD or B.1.1.7, B.1.351, P.1, B.1.617.1, B.1.617.2 mutant and treated with the neutralizing antibody at increasing concentration. Percent inhibition is calculated based on the OD value.
Detection of HRP-SARS-CoV-2 Spike RBD(B.1.1.529/Omicron), His Tag titer by compitive-ELISA Assay.Serial dilutions of Anti-SARS-CoV-2 Spike RBD Neutralizing Antibody, Chimeric mAb, Human IgG1 (AM122) (Trehalose free) (Cat. No. S1N-M12A1) were added into Human ACE2 / ACEH Protein, Fc Tag (Cat. No. AC2-H5257): HRP-SARS-CoV-2 Spike RBD(B.1.1.529/Omicron), His Tag binding reactions. The half maximal inhibitory concentration (IC50) is 0.340 μg/mL (Routinely tested).
