(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
Activity
Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1-RBD at 2 ¥ìg/ml can bind Biotinylated Anti-SARS-CoV-2-S Antibody (CSB-RA33245D1GMY), the EC50 is 106.2-131.2 ng/ml.
(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
Activity
Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV S-RBD at 2 ¥ìg/ml can bind Paguma larvata ACE2 (CSB-MP684964PAL), the EC50 is 5.056-7.559 ng/ml.
This assay employs the competitive inhibition ELISA for the qualitative determination of SARS-CoV-2 neutralizing antibody concentrations in serum, plasma. The standard curve is provided for demonstration only. It should be generated for each set of samples assayed.
