Recombinant COVID-19 Envelope protein, His-tagged

• Cat.No.: Envelope-302V
• Product Overview: Recombinant COVID-19 Envelope protein (Met1-Val75) was fused to His-tag at the C-terminus and expressed in E.coli.

Specification

• Species: Sars-CoV-2
• Source: E.coli
• Tag: His
• Protein Length: Met1-Val75
• Description: The COVID-19 is composed of a double-layered lipid envelope, including Spike glycoprotein (S), Envelope protein (E), Membrane glycoprotein (M), and Nucleocapsid protein (Nucleocapsid protein, N). Among them, The amino acid sequence of the COVID-19 envelope protein is 95% identical of the SARS envelope protein.
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Molecular Mass: The protein has a calculated MW of 9.6 kDa.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade 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 0.2 mg/ml. Centrifuge the vial at 4℃ before opening to recover the entire contents.
