Source

MERS Spike protein trimer, His Tag (SPN-M52H4) is expressed from human 293 cells (HEK293). It contains AA Tyr 18 - Trp 1295 (Accession # K9N5Q8-1). The recombinant protein has a T4 fibritin trimerization motif. Proline substitutions (V1060P, L1061P) and alanine substitutions (R748A, R751A) are introduced to stabilize the trimeric prefusion state of MERS-CoV Spike protein and abolish the furin cleavage site, respectively.
Predicted N-terminus: Tyr 18

Molecular Characterization

Online(Tyr 18 - Trp 1295) K9N5Q8-1Development Suggestion
This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 145.9 kDa. The protein migrates as 150 kDa and 175-200 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Purity

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS. Normally trehalose is added as protectant before lyophilization.
