• Cat.No.: Spike-392V
• Product Overview: Recombinant COVID-19 S1 (P681H) protein(YP_009724390.1)(Val 16 - Arg 685), fused to His tag at the C-terminus, was expressed in HEK293.

Specification

• Species: Sars-CoV-2
• Source: HEK293
• Tag: His
• Protein Length: Val 16 - Arg 685
• Description: It's been reported that SARS-CoV-2 can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
• Molecular Mass: The protein has a calculated MW of 76.8 kDa.
• Storage: For long term storage, the product should be stored at lyophilized state at -20°C or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20°C to -70°C for 12 months in lyophilized state;
  -70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
