  • Synonym
    B7-H4,VTCN1,B7S1,B7h.5
  • Source
    Azide-labeled Mouse B7-H4 Protein, His Tag(B74-M52H7) is expressed from human 293 cells (HEK293). It contains AA Leu 25 - Gly 257 (Accession # Q7TSP5-1 ).
  • Molecular Characterization
    B7-H4 Structure

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

    The protein has a calculated MW of 40.3 kDa. The protein migrates as 60-80 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • 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 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

  • Background
    V-set domain-containing T-cell activation inhibitor 1 (VTCN1) is also known as Immune costimulatory protein B7-H4, Protein B7S1, T-cell costimulatory molecule B7x, B7H4, which belongs to the immunoglobulin superfamily and BTN/MOG family. VTCN1 contains two Ig-like V-type (immunoglobulin-like) domains. The expression of VTCN1 is up-regulated by IL6 and IL10 and is inhibited by GM-CSF and IL4 on antigen-presenting cells (APCs). VTCN1 / B7-H4 negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. VTCN1 involved in promoting epithelial cell transformation.
