Human BST1 Protein, His Tag (MALS verified)

  • Synonym
    ADP-ribosyl cyclase 2, CD157
  • Source
    Human BST1, His Tag (BS1-H52H9) is expressed from human 293 cells (HEK293). It contains AA Gly 29 - Ala 293 (Accession # Q10588-1).
    Predicted N-terminus: Gly 29
  • Molecular Characterization
    Online(Gly 29 - Ala 293) Q10588-1

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

    The protein has a calculated MW of 32.1 kDa. The protein migrates as 35-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

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

    Contact us for customized product form or formulation.

  • 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

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.

The purity of Human BST1, His Tag (Cat. No. BS1-H52H9) is more than 90% and the molecular weight of this protein is around 80-95 kDa verified by SEC-MALS.

  • Background
    Bone marrow stromal cell antigen-1(BST-1) or CD157 is a stromal cell line-derived glycosylphosphatidylinositol-anchored molecule that belongs to the CD38 family. CD157 was discovered in a bone marrow stromal cell line where it facilitates pre-B-cell growth.BST1 expression is enhanced in bone marrow stromal cell lines derived from patients with rheumatoid arthritis. The polyclonal B-cell abnormalities in rheumatoid arthritis may be, at least in part, attributed to BST1 overexpression in the stromal cell population.
