  • Source
    MERS Spike protein trimer (R748A, R751A, V1060P, L1061P), His Tag (SPN-M52H5) is expressed from human 293 cells (HEK293). It contains AA Tyr 18 - Trp 1295 (Accession # K0BRG7 (R748A, R751A, V1060P, L1061P)). 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
    Spike protein Structure

    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 with trehalose as protectant.

  • Background
    The MERS or Middle East Respiratory Syndrome Coronavirus, is a member of the coronavirus family and is known to cause severe respiratory illness in humans. The MERS protein is a type I transmembrane protein that plays a vital role in the virus's ability to infect host cells. It is composed of three main domains: the extracellular domain, the transmembrane domain, and the cytoplasmic domain. The extracellular domain, further divided into S1 and S2 subunits, is responsible for receptor recognition and binding. The S1 subunit contains the Receptor Binding Domain (RBD), which is crucial for the virus's attachment to and entry into host cells. The RBD specifically interacts with the host cell receptor, facilitating the initial step of infection. The S2 subunit, on the other hand, is responsible for membrane fusion. It contains a fusion peptide that inserts into the host cell membrane, initiating the fusion process. This fusion allows the virus's genetic material to be released into the host cell, initiating the infection process.
