Applications
ELISA, SDS-PAGE
Expression System
HEK293 cells
Nature
Recombinant
Protein Species
SARS-CoV-2
Protein Length
Protein fragment.
Sequence
S1 protein NTD (Ser13-Leu303) + hFc (Glu99-Ala330)
Tag
C-terminal Human Fc Tag
Molecular Weight
The protein has a predicted molecular mass of 59.0 kDa after removal of the signal peptide. The apparent molecular mass of S1-NTD-hFc is approximately 70-100 kDa due to glycosylation.
