- Format
- Lyophilized
- Reconstitution
- 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.
- Buffer
- Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.

- Background
- S1 protein NTD,Spike glycoprotein Subunit1 NTD,S glycoprotein Subunit1 NTD,Spike protein S1 NTD,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.
- Molecular Weight
- 35 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Tris-Bis PAGE result.
