Recombinant SARS-CoV-2 pike protein, His-Flag-tagged

• Cat.No.: Spike-941V
• Product Overview: Recombinant 2019 nCOV Spike S1 Protein NTD is expressed from Expi293 with a His tag and flag tag at the C-terminal. It contains Ser13-Lys304.

Specification

• Species: SARS-CoV-2
• Source: HEK293
• Tag: Flag&His
• Protein Length: It contains Ser13-Lys304.
• Description: 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.
• Form: Supplied as 0.22um filtered solution in PBS (pH 7.4).
• Molecular Mass: The protein has a predicted MW of 35 kDa. Due to glycosylation, the protein migrates to 55-70KDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 1EU 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°C. 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 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
