Amount : 100 μg
Purification : >95% by SDS-PAGE.
Content : Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water.
Storage condition : Store the lyophilized protein at -20°C to -80 °C for long term. After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week. Avoid repeated freeze/thaw cycles.
AA sequence : The target protein is expressed with sequence (Gln14-Arg683) of 2019-ncov Spike S1 fused with a 6×His tag and Avi at the C-terminus.
Gene ID : 43740568
Alternative Name : S1 protein; Spike glycoprotein Subunit1; S glycoprotein Subunit1; Spike protein S1; novel coronavirus s1 Protein

Source: HEK 293 cells. 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.

Bio-Activity: Measured by its binding ability in a functional ELISA. Immobilized Recombinant 2019-nCoV Spike S1-His at 2μg/mL (100 μL/well) can bind Recombinant Human ACE2 with a linear range of 1.5-15 ng/mL. Endotoxin : < 1.0 EU/μg of the protein by LAL method.

For Research Use Only. Not for use in diagnostic/therapeutics procedures.
