Recombinant Protein;25UG;Biotinylated SARS-CoV-2 Spike S1, His,Avitag (S1N-C82E5) is expressed from human 293 cells (HEK293). It contains AA Val 16 - Arg 685 (Accession # QHD43416.1). The mutations (T19R, G142D, EF156-157del, R158G, L452R, T478K, D614G, P681R) were identified in the SARS-CoV-2 variants which emerged in India (known as B.1.617.2).;This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag. The protein has a calculated MW of 78.4 kDa. The protein migrates as 100-120 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.;Immobilized Anti-SARS-CoV-2 Spike RBD Antibody, Chimeric mAb, Human IgG1 (Cat. No. S1N-M122) at 1 μg/mL (100 μL/well) can bind Biotinylated SARS-CoV-2 Spike S1, His,Avitag (Cat. No. S1N-C82E5) with a linear range of 0.2-6 ng/mL (QC tested).;Immobilized Biotinylated SARS-CoV-2 Spike S1, His,Avitag (Cat. No. S1N-C82E5) at 1 μg/mL (100 μL/well) on streptavidin (Cat. No. STN-N5116) precoated (0.5 μg/well) plate can bind Huma
