SARS-CoV monoclonal Spike S1 VHH neutralizing antibody, a.a. 1-127(full length), with C-terminal Avi-Tag fused to the Fc portion of Human IgG1, expressed in a HEK293 cell expression system. MW = 43 kDa. VHHs are single-domain antibodies from camelids.
assay conditions: Inhibition of ACE2:SARS-CoV-1 Spike binding by a small anti-SARS-CoV-1 Spike antibody, VHH (BPS Bioscience, #100784). A small anti-SARS-CoV-1 Spike antibody was evaluated using the SARS-CoV-1 Spike Trimer (S1+S2):ACE2 Inhibitor Screening Colorimetric Assay Kit (BPS Bioscience, #79999). The antibody was serially diluted in 1x Immuno Buffer (BPS Bioscience, #79311) and tested following the assay kit protocol.
Formulation
8 mM Phosphate, pH 7.4, 110 mM NaCl, 2.2 mM KCl, and 20% glycerol.
