  • Synonym
    B7-H7,HHLA2,B7 Homolog 7
  • Source
    Biotinylated Human B7-H7, Fc,Avitag (B77-H82F5) is expressed from human 293 cells (HEK293). It contains AA Ile 23 - Asn 344 (Accession # Q9UM44-1).
    Predicted N-terminus: Ile 23
  • Molecular Characterization
    Online(Ile 23 - Asn 344) Q9UM44-1

    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 65.9 kDa. The protein migrates as 80-90 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 0.45-1 as determined by the HABA assay.
  • 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 Tris with Glycine, Arginine and 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 was 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.
