HCoV-NL63 S protein, His Tag

  • Synonym
    Spike,S protein,Spike glycoprotein,S glycoprotein
  • Source
    HCoV-NL63 Spike Trimer, His Tag (SPN-H52H4) is expressed from human 293 cells (HEK293). It contains Phe 16 - Asn 1291 (Accession # Q6Q1S2-1).The recombinant protein is expressed from human 293 cells (HEK293) with T4 fibritin trimerization motif and a polyhistidine tag at the N-terminus.
    Predicted N-terminus: Phe 16
  • Molecular Characterization
    Online(Phe 16 - Asn 1291) Q6Q1S2-1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 146.9 kDa. The protein migrates as 200-240 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.

  • Formulation

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

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
HCoV-NL63 S protein, His Tag (Cat. No. SPN-H52H4) SDS-PAGE gel

HCoV-NL63 S protein, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

  • Background
    Human coronavirus NL63 (HCoV-NL63) is one of seven known coronaviruses to infect humans. The virus is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to ACE2. Infection with the virus has been confirmed worldwide, and has an association with many common symptoms and diseases. The spike protein of HCoV-NL63 is a trimer protruding from the viral membrane to engage cellular receptors and mediate viral fusion with host membranes. Each spike trimer contains two large regions: N-terminal S1 responsible for receptor binding and C-terminal S2 responsible for fusion.
