Human pIgR Protein, His Tag

  • シノニム
    PIGR,Poly-Ig receptor
  • ソース
    Human pIgR, His Tag (PIR-H5222) is expressed from human 293 cells (HEK293). It contains AA Lys 19 - Arg 638 (Accession # AAI10495.1).
    Predicted N-terminus: Lys 19
  • 分子特性
    Online(Lys 19 - Arg 638) AAI10495.1

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

    The protein has a calculated MW of 68.7 kDa. The protein migrates as 90-100 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.

  • 成分

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

SDS-PAGE
Human pIgR, His Tag (Cat. No. PIR-H5222) SDS-PAGE gel

Human pIgR, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.

  • バックグラウンド
    Polymeric immunoglobulin receptor (PIGR) is also known as Poly-Ig receptor, which can be cleaved into membrane secretory component (SC). PIGR is a type I transmembrane glycoprotein or a member of the immunoglobulin superfamily, and is synthesized by secretory epithelial cells and delivered to the basolateral plasma membrane where it can bind larger polymers of IgA (pIgA ) and pentameric IgM. The complex is then transported across the cell to be secreted at the apical surface. During this process a cleavage occurs that separates the extracellular (known as the secretory component) from the transmembrane segment.
