Biotinylated Human B7-H3 / CD276 Protein, Fc Tag, Avi Tag (Avitag™)

  • Synonym
    B7-H3,CD276,B7 homolog 3
  • Source
    Biotinylated Human B7-H3, Fc Tag, Avi Tag (B73-H82F5) is expressed from human 293 cells (HEK293). It contains AA Leu 29 - Pro 245 (Accession # Q5ZPR3-2).
    Predicted N-terminus: Leu 29
  • Molecular Characterization
    B7-H3(Leu 29 - Pro 245) Q5ZPR3-2

    This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag™).

    The protein has a calculated MW of 51.6 kDa. The protein migrates as 63-70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Biotinylation
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Biotin:Protein Ratio
    The biotin to protein ratio is 0.5-1 as determined by the HABA assay.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 49 mM Tris, 100 mM Glycine, 25 mM Arg, 150 mM NaCl, pH7.5. 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

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

    Please avoid repeated freeze-thaw cycles.

    No activity loss is observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;

    2. -70°C for 3 months under sterile conditions after reconstitution.

SDS-PAGE
Biotinylated Human B7-H3, Fc Tag, Avi Tag (Cat. No. B73-H82F5) SDS-PAGE gel

Biotinylated Human B7-H3, Fc Tag, Avi Tag on SDS-PAGE  under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

  • Background
    B7 homolog 3 (B7-H3), a member of the immunoglobulin superfamily, is also known CD276, which contains two Ig-like C2-type (immunoglobulin-like) domains and two Ig-like V-type (immunoglobulin-like) domains. B7-H3 may participate in the regulation of T-cell-mediated immune response. B7-H3 also plays a protective role in tumor cells by inhibiting natural-killer mediated cell lysis as well as a role of marker for detection of neuroblastoma cells. Furthermore, B7-H3 is involved in the development of acute and chronic transplant rejection and in the regulation of lymphocytic activity at mucosal surfaces. It could also play a key role in providing the placenta and fetus with a suitable immunological environment throughout pregnancy.
