Recombinant 2019-nCoV (2019 novel coronavirus) Spike protein S1, His/Avi-tagged

• Cat.No.: Spike-200V
• Product Overview: Recombinant 2019-nCoV (2019 novel coronavirus) Spike protein S1 (Gln14-Arg683) was expressed from mammalian with a His tag and Avi at the C-terminal.

Specification

• Species: Sars-Cov-2
• Source: Mammalian Cells
• Tag: Avi&His
• Protein Length: 670
• Description: The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensinconverting 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.
• Form: Supplied as 0.22μm filtered solution in PBS (pH 7.4).
• Molecular Mass: The protein has a predicted MW of 77.9 kDa. Due to glycosylation, the protein migrates to 110-120 kDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 1 EU per ug by the LAL method.
• Purity: >95% as determined by Bis-Tris PAGE; >95% as determined by HPLC.
• Storage: The product should be stored at -70 centigrade. Please do not repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 mg/ml. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
• Warning: For Research Use Only.
