Recombinant Protein;100UG;SARS-CoV-2 S protein RBD (W436R), His Tag (SPD-S52H7) is expressed from human 293 cells (HEK293). It contains AA Arg 319 - Phe 541 (Accession # QHD43416.1 (W436R)).;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 2 μg/mL (100 μL/well) can bind SARS-CoV-2 S protein RBD (W436R), His Tag (Cat. No. SPD-S52H7) with a linear range of 2-31 ng/mL (QC tested).;Immobilized SARS-CoV-2 S protein RBD (W436R), His Tag (Cat. No. SPD-S52H7) at 2 μg/mL (100 μL/well) can bind Monoclonal Anti-SARS-CoV-S protein RBD Antibody, Human IgG1 with a linear range of 0.1-3 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 (W436R), His Tag (Cat. No. SPD-S52H7) with an affini
