Recombinant Protein;1MG;SARS-CoV-2 S protein RBD (V483A), His Tag (SPD-C52H5) is expressed from human 293 cells (HEK293). It contains AA Arg 319 - Phe 541 (Accession # QHD43416.1 (V483A)).;This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 27.0 kDa. The protein migrates as 33-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.;Immobilized Human ACE2, Fc Tag (Cat. No. AC2-H5257) at 1 μg/mL (100 μL/well) can bind SARS-CoV-2 S protein RBD (V483A), His Tag (Cat. No. SPD-C52H5) with a linear range of 2-16 ng/mL (QC tested).;Immobilized Anti-SARS-CoV-2 Neutralizing Antibody, Human IgG1 (Cat. No. SAD-S35) at 1 μg/mL (100 μL/well) can bind SARS-CoV-2 S protein RBD (V483A), His Tag (Cat. No. SPD-C52H5) with a linear range of 2-16 ng/mL (Routinely tested).;Human ACE2, Fc Tag (Cat. No. AC2-H5257) captured on CM5 chip via Anti-human IgG Fc antibodies surface can bind SARS-CoV-2 S protein RBD (V483A), His Tag (Cat. No. SPD-C52H5) with an
