- 状态
- Lyophilized
- 溶解方式
- Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.
- 缓冲液
- Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.
- 储存条件
- 4 °C,-80 °C
- 储存方法
- 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.

- Abstract
- SARS-CoV-2 Spike 产品
- 别名
- E2 Protein, E2 glycoprotein precursor Protein, Surface Glycoprotein Protein, S Protein
- 背景
- S protein, Spike glycoprotein, S glycoprotein, COVID-19,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.
- 分子量
- 136.6 kDa. Due to glycosylation, the protein migrates to 175-230 kDa based on Tris-Bis PAGE result.
