• The recombinant RBD-hFc protein migrates as 70kDa due to glycosylation
  • The purity of 2019-nCoV Spike RBD Fc is greater than 95% as determined by SEC-HPLC.

2019 nCoV/COVID19 RBD protein (Recombinant) (hFc-Tag) (STJP000262)


Current Stock:
Host: CHO cells
Short Description: Recombinant-2019 nCoV/COVID19 RBD-hFc-Tag protein was developed from cho cells and has a target region of hFc-Tag. For use in research applications.
Conjugation: Unconjugated
Formulation: Recombinant COVID-19 RBD (Receptor Binding Domain) protein was lyophilized from 0.2 µm filtered 20 mM Tris, 300 mM NaCl, 10 % glycerol, pH 8.0.
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: 319-514 aa
Background Recombinant 2019-nCoV RBD protein is a protein consisting of 460 amino acid residues, due to glycosylation migrates as an approximately 70 kDa protein on SDS-PAGE.
