Recombinant SARS Spike S1 Protein C-Fc-Avi

SARS Spike S1蛋白;S protein,Spike glycoprotein,S glycoprotein

SARS

Mammalian

The protein has a predicted MW of 100.6 kDa. Due to glycosylation, the protein migrates to 120-140KDa based on Bis-Tris PAGE result.

Lyophilized from 0.22um filtered solution in PBS (pH 7.4).Normally 5 % trehalose is added as protectant before lyophilization.

Ser14-Arg667

> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC

Less than 1 EU per μg by the LAL method.

Centrifuge tubes before opening.Reconstitute no more than 1 mg/mL according to the size in deionized water.

Within 1 month, 2 to 8 °C under sterile conditions after reconstitution. 12 months from date of receipt, -20 to -80 °C as supplied. Avoid repeated freeze-thaw cycles.

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.
