| The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity. |
| Recombinant SARS-Cov-2 Spike RBD (Omicron BA.2.12.1) Protein is expressed from Expi293 with His tag at the C-terminal. It contains Arg319-Phe541(G339D, S371F, S373P, S375F, T376A, D405N, R408S, K417N, N440K, L452Q, S477N, T478K, E484A, Q493R, Q498R, N501Y, Y505H). |

| The protein has a predicted MW of 26.09 kDa. Due to glycosylation, the protein migrates to 38-48 kDa based on the Tris-Bis PAGE result. |
| Immobilized SARS-CoV-2 Spike RBD (Omicron BA.2.12.1) , His Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Human ACE2, hFc Tag with the EC50 of 14.3ng/ml determined by ELISA. See testing image for detail. |
| C-His |
| Expi293 |
| > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| Less than 1EU per ug by the LAL method. |
| Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as a protectant before lyophilization. |
| Reconstituted protein stable at -80 C for 12 months, 4 C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
| Shipped at ambient temperature. |
| Centrifuge tubes before opening. Reconstituting to a concentration of more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
