Biotinylated Human TNF-alpha Protein, His,Avitag™ (HPLC-verified)

  • Synonym
  • Source
    MABSol® Biotinylated Human TNF-alpha, His,Avitag (HPLC-verified) (TNA-H82E3) is expressed from human HEK293 cells. It contains AA Val 77 - Leu 233 (Accession # NP_000585.2).
    Predicted N-terminus: Val 77
  • Molecular Characterization
    Online(Val 77 - Leu 233) NP_000585.2

    This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 19.2 kDa. The protein migrates as 21 kDa on a SDS-PAGE gel under reducing (R) condition 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.

    >95% as determined by SEC-HPLC.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    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.

    No activity loss was observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;

    2. -70°C for 12 months under sterile conditions after reconstitution.
