Biotinylated Human TL1A / TNFSF15 Protein, His,Avitag™

Recommended Hot Products:

Based on the high binding affinity between biotin-streptavidin systems, our Streptavidin series products are recommended to use together with biotinylated proteins to get lower non-specific binding results in a shorter time.

  • Synonym
    TL1A, VEGI-251, TNFSF15
  • Source
    Biotinylated Human TL1A Protein, His,Avitag(TLA-H52Q1) is expressed from human 293 cells (HEK293). It contains AA Leu 72- Leu 251 (Accession # O95150-1 ).
    Predicted N-terminus: His
  • Molecular Characterization
    TL1A Structure

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

    The protein has a calculated MW of 24.1 kDa. The protein migrates as 28-32 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Labeling
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Protein Ratio
    Passed as determined by the HABA assay / binding ELISA.
  • 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

    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.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
TL1A SDS-PAGE

Biotinylated Human TL1A Protein, His,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

Bioactivity-ELISA
 TL1A ELISA

Immobilized Human DcR3, Fc Tag (Cat. No. TNB-H5255) at 5 μg/mL (100 μL/well) can bind Biotinylated Human TL1A / TNFSF15, His,Avitag (Cat. No. TLA-H52Q1) with a linear range of 0.2-6 ng/mL (QC tested).

 TL1A ELISA

Immobilized Biotinylated Human TL1A / TNFSF15, His,Avitag (Cat. No. TLA-H52Q1) at 1 μg/mL (100 μL/well) on streptavidin (Cat. No. STN-N5116) precoated (0.5 μg/well) plate can bind Human DcR3, Fc Tag (Cat. No. TNB-H5255) with a linear range of 0.1-3 ng/mL (Routinely tested).

  • Background
    TNF-like cytokine 1A (TL1A) and its receptors, death receptor 3 (DR3) and decoy receptor 3 (DcR3) are members of the TNF and TNF receptor superfamilies of proteins, respectively. Binding of APC-derived TL1A to lymphocytic DR3 provides co-stimulatory signals for activated lymphocytes. DR3 signaling affects not only the proliferative activity of and cytokine production by effector lymphocytes, but also critically influences the development and suppressive function of regulatory T-cells. Whereas, DcR3 restricts the function of the TL1A/DR3 complex: attenuating T-cell activation and downregulating the secretion of pro-inflammatory cytokines. Together with DR3 and DcR3, TL1A constitutes a cytokine system that actively interferes with the regulation of immune responses.
