Antibody;100UG;Mouse IgG1/kappa;This product is a specific antibody against SARS-CoV-2 Spike protein RBD domain. No cross-reactivity is deteced with Spike protein RBD domain of other coronaviruses, including SARS-CoV, MERS-CoV, HCoV-229E, HCoV-NL63, HCoV-OC43 and HCoV-HKU1.;Mouse monoclonal antibody is produced from a hybridoma resulting from fusion of SP2/0 myeloma and B-lymphocytes obtained from a mouse immunized with S1 protein F(ab')2.;This protein . As a result of Glycosylation, the protein migrates as 26 kDa and 55 kDa under reducing (R) condition, and 130 kDa under non-reducing (NR) condition (SDS-PAGE).;Immobilized SARS-CoV-2 S protein RBD, His Tag (Cat. No. SPD-C52H1) at 2 μg/mL (100 μL/well) can bind Anti-SARS-CoV-2 Spike S1 Antibody, Mouse IgG1 (Cat. No. S1N-S58A1) with a linear range of 0.08-3 ng/mL (QC tested).
