Biotinylated Human APRIL / TNFSF13 Protein, Fc,Avitag™

  • Synonym
    APRIL,TNFSF13,TALL-2,TRDL-1,CD256,TALL2,ZTNF2
  • Source
    Biotinylated Human APRIL, Fc,Avitag (APL-H82F5) is expressed from human 293 cells (HEK293). It contains AA Ala 105 - Leu 250 (Accession # O75888-1).
    Predicted N-terminus: Pro
  • Molecular Characterization
    Online(Ala 105 - Leu 250) O75888-1

    This protein carries a human IgG1 Fc tag at the N-terminus, followed by an Avi tag.

    The protein has a calculated MW of 44.6 kDa. The protein migrates as 45-50 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 Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • Background
    APRIL(a proliferation-inducing ligand) is also known as Tumor necrosis factor ligand superfamily member 13, TALL-2, TRDL-1, CD256, TNFFSF 13, cytokine that binds to TNFRSF13B/TACI and to TNFRSF17/BCMA. APRIL is a cytokine of the tumor necrosis factor family associated mainly with hematologic malignancies. The closely related TNF family ligands B cell activation factor (BAFF) and a proliferation-inducing ligand (APRIL) serve in the generation and maintenance of mature B-lymphocytes. Both BAFF and APRIL assemble as homotrimers that bind and activate several receptors that they partially share. BAFF-APRIL heteromers of different stoichiometries have distinct receptor-binding properties and activities. In addition, expression of APRIL was regulated by miR-145 in GC cells.
