Key Properties
−| Source | CHO-based cell line (expressed by QMCF Technology) |
|---|---|
| Molecular Weight | 417.33 kDa; Protein contains amino acids 14-1211, plus two extra amino acids (AS) in N-terminus, trimerization domain and His-6 tag at C-terminus, GS linker between protein and trimerization domain and GSG linker between trimerization domain and His-tag. Furin cleavage (RRAR) site between Spike S1 and S2 is mutated (GSAS). Also, two stabilizing prolines (PP) have been added to the S2 domain. |
| Purification | Metal-affinity chromatography following gel filtration. Protein is sterile-filtrated through 0.22 µm filter. |
