  • Synonym
    BTLA,CD272
  • Source
    Human BTLA, Fc Tag(BTA-H5256) is expressed from human 293 cells (HEK293). It contains AA Lys 31 - Ser 150 (Accession # AAP44003.1).
    Predicted N-terminus: Lys 31
  • Molecular Characterization
    BTLA Structure

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 40.4 kDa. The protein migrates as 52-65 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

    >95% as determined by SDS-PAGE.

    >95% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

Bioactivity-ELISA
 BTLA ELISA

Immobilized Human HVEM, His Tag (Cat. No. HVM-H52E9) at 5 μg/mL (100 μL/well) can bind Human BTLA, Fc Tag (Cat. No. BTA-H5256) with a linear range of 0.01-0.313 μg/mL (QC tested).

  • Background
    B- and T-lymphocyte attenuator (BTLA) is also known as B- and T-lymphocyte-associated protein, CD antigen CD272. BTLA contains one Ig-like V-type (immunoglobulin-like) domain. As a lymphocyte inhibitory receptor, BTLA / CD272 inhibits lymphocytes during immune response. BTLA / CD272 can interact with tyrosine phosphatases PTPN6/SHP-1 and PTPN11/SHP-2, and interact with TNFRSF14/HVEM.
