The SARS-CoV-2 spike (S) protein is the target of vaccine design efforts to end the COVID-19 pandemic. Despite a low mutation rate, isolates with the D614G substitution in the S protein appeared early during the pandemic, and are now the dominant form worldwide. Here, we analyze the D614G mutation in the context of a soluble S ectodomain construct.

| 种属 | SARS-CoV-2 |
| 表达系统 | HEK293 Cells |
| 标签 | C-His-Avi |
| 蛋白编号 | A0A6G7K2L4 |
| 别名 | Spike,S1 protein,Spike protein S1,S1 protein,S glycoprotein Subunit1 |
| 蛋白构建 | Gln14-Arg683(D614G) |
| 蛋白纯度 | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| 分子量 | 77.9 kDa (predicted). Due to glycosylation, the protein migrates to 110-120 kDa based on Tris-Bis PAGE result. |
| 内毒素 | < 1 EU/μg by the LAL method. |
| 蛋白性状 | Lyophilized powder |
| 缓冲液 | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
| 复溶方法 | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| 存储 | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| 运输方式 | In general, Lyophilized powders are shipping with blue ice. |
