Recombinant COVID-19 Spike RBD + SD1 protein, His-tagged

• Cat.No.: Spike-209V
• Product Overview: Recombinant COVID-19 spike protein receptor binding domain and subdomain (Arg319-Ser591), fused to His-tag at the C-terminus, was expressed in HEK293F.

Specification

• Species: COVID-19
• Source: HEK293
• Tag: His
• Description: It's been reported that COVID-19 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.
• Form: Liquid in sterile PBS, pH 7.4.
• Molecular Mass: Predicted molecular weight: 31.8 kDa
• Endotoxin: <0.1 EU per ug of protein as determined by LAL method.
• Purity: 90% or above
• Storage: The protein is stable in a liquid state at -70 centigrade for 12 months. Avoid repeated freeze-thaw cycles.
• Concentration: See product label
• Shipping: Recombinant proteins are provided as frozen liquid and will be shipped out with dry ice.
• Warning: For research use only.
