Figure 1. Coomassie-stained SDS-PAGE analysis of SARS-COV-2 S1 RBD. 4-15% gradient gel is used for analysis. Lane 1. 1.3μg of SARS-CoV-2 S1 RBD. Lane 2. Protein size marker (Smobio).
Figure 2. Binding analysis of the SARS-CoV-2 S1 RBD protein to hACE2 receptor. hACE2 -Fc protein was bound to Protein G sensor. 25 to 200 nanomols of SARS-CoV-2 S1 RBD protein was bound to the ACE2 receptor.
