  • Synonym
    B7-H4,VTCN1,B7S1,B7h.5
  • Source
    Biotinylated Human B7-H4, Avitag,His Tag (recommended for biopanning) (B74-H82E2) is expressed from human 293 cells (HEK293). It contains AA Phe 29 - Ala 258 (Accession # NP_078902).
    Predicted N-terminus: Phe 29
  • Molecular Characterization
    Online(Phe 29 - Ala 258) NP_078902

    This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag.

    The protein has a calculated MW of 28 kDa. The protein migrates as 45-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Application
    B74-H82E2 works best for experiments that test the binding between B7-H4 and candidate antibodies, such as biopanning and other relevant assays.
  • Biotinylation
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • 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 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.

    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.
