COV2 Spike protein S B.1.1.529 (Omicron) protein (Recombinant) (His-Tag) (STJP000274)


Current Stock:
Host: HEK293
Short Description: Recombinant-COV2 Spike protein S B.1.1.529 (Omicron)-His-Tag protein was developed from hek293 and has a target region of His-Tag. For use in research applications.
Conjugation: Unconjugated
Formulation: Recombinant COVID-19 Spike was lyophilized from 0.2 µm filtered PBS solution pH7.4
Dilution Range: Spin the vial and reconstite in distilled water to a concentration not less than 0.1 mg/mL. This can then be diluted into other buffers.
Storage Instruction: The lyophilized protein is stable for at least 2 years from date of receipt at-20°C.
Endotoxin: Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg (1EU/µg).
Immunogen Region: ECD
Background Recombinant NCOV Spike protein B.1.1.529 encodes the NCOV spike glycoprotein S1+S2 sequences. Recombinant COV2 Spike migrates due to glycosylation as an approximately 130 kDa protein under reducing conditions in SDS-PAGE.
