Biotinylated Human BTLA (31-134) Protein, Fc Tag, Avi Tag (Avitag™)

  • Synonym
    BTLA,CD272
  • Source
    Biotinylated Human BTLA (31-134), Fc Tag (BTA-H82F8) is expressed from human 293 cells (HEK293). It contains AA Lys 31 - Thr 134 (Accession # Q7Z6A9).
    Predicted N-terminus: Lys 31
  • Molecular Characterization
    BTLA(Lys 31 - Thr 134) Q7Z6A9

    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 40.5 kDa. The protein migrates as 55-66 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 50 mM Tris, 100 mM Glycine, 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 BTLA (31-134), Fc Tag (Cat. No. BTA-H82F8) SDS-PAGE gel

Biotinylated Human BTLA (31-134), Fc 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%.

Bioactivity
Biotinylated Human BTLA (31-134), Fc TagBiotinylated Human BTLA (31-134), Fc Tag (Cat. No. BTA-H82F8) ELISA bioactivity

Immobilized Human HVEM, Fc Tag (Cat. No. HVM-H5258) at 10 μg/mL (100 μL/well) can bind Biotinylated Human BTLA, Fc Tag (Cat. No. BTA-H82F8) with a linear range of 0.3-5 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.
