• Cat.No.: Spike-11V
• Product Overview: Recombinant COVID-19 Spike NTD(HV69-70del, Y144del) protein(QHD43416.1)(Ser 13 - Leu 303), fused with His tag, was expressed in HEK293.

Specification

• Species: Sars-CoV-2
• Source: HEK293
• Tag: His
• Protein Length: Ser 13 - Leu 303
• 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 34.5 kDa. The protein migrates as 50-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
  >90% as determined by SEC-MALS.
• Storage: 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 to reconstitute the lyophilized powder in sterile water to 100-200 ug/ml, and further dilute with other solvents. The dissolved protein can be stored at 4°C for 2-7 days and should be used up as soon as possible. If not in use for a short time, please store at -20°C.
