SARS-CoV-2 S protein RBD (N501Y), Fc Tag (MALS verified)

  • シノニム
    Spike,S protein RBD,Spike glycoprotein Receptor-binding domain,S glycoprotein RBD,Spike protein RBD
  • ソース
    SARS-CoV-2 S protein RBD (N501Y), Fc Tag (SPD-C5253) is expressed from human 293 cells (HEK293). It contains AA Arg 319 - Lys 537 (Accession # QHD43416.1(N501Y)). The N501Y mutation was identified in the SARS-CoV-2 variant (known as B.1.1.7, 20B/501Y.V1 or VOC 202012/01) which emerged in the United Kingdom.
    Predicted N-terminus: Arg 319
  • 分子特性
    Online(Arg 319 -  Lys 537) QHD43416.1 (N501Y)

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 51.1 kDa. The protein migrates as 55-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • エンドトキシン
    Less than 1.0 EU per μg by the LAL method.
  • 純度

    >95% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • 成分

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • バックグラウンド
    It's been reported that Coronavirus can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
