EG-303
|
| Description |
A recombinant form of the full length
spike glycoprotein from severe acute respiratory syndrome-related
coronavirus 2 (SARS-CoV-2), Wuhan-Hu-1 (GenPept: QHD43416) was produced
in HEK293 cells and purified by nickel affinity and ion exchange
chromatography. This recombinant protein has been stabilized by several
mutations: removing the polybasic S1/S2 cleavage site (RRAR to A,
residues 682 to 685); K986P and V987P; adding a T4 foldon
trimerization domain followed by a hexa-histidine tag at the
C-terminus.
This protein forms a trimer, which is suitable for screening of
neutralizing antibodies in vitro |
