| 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 S1 (Omicron BA.4/BA.5/BA.5.2) Protein is expressed from Expi293 with His tag at the C-terminal. It contains Gln14-Arg683(T19I, L24S, PPA25-27del, HV69-70del, G142D, V213G, G339D, S371F, S373P, S375F, T376A, D405N, R408S, K417N, N440K, L452R, S477N, T478K, E484A, F486V, Q498R, N501Y, Y505H, D614G, H655Y, N679K, P681H). |

| > 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. |
