Accession Number	QHD43416
Expressed Region	Arg319-Phe541. Omicron 15 mutant sites (G339D, S371L, S373P, S375F, K417N, N440K, G446S, S477N, T478K, E484A, Q493R, G496S, Q498R, N501Y, Y505H)
Molecular Weight (kDa)	Recombinant protein product has a calculated molecular mass of ∼25 kDa. Due to the abundant glycosylation, it migrates as approximately ∼30 kDa protein bands in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions. After deglycosylation under native and denature conditions, the protein presented as one reduced ∼25 kDa band.
Storage/Stability	Upon arrival, the protein may be stored for 2 weeks at 4 °C. For long term storage, it is recommended to store at -20 °C or -80 °C in appropriate aliquots. Avoid repeated freeze-thaw cycles.
