Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Upon reconsitution add a carrier protein (0.1% BSA). Store at -20°C or -80°C. Avoid freeze / thaw cycle. Store In the Dark.

    pH: 7.40
    Constituents: PBS, 5% Trehalose

    0.22 µm filtered

    This product is an active protein and may elicit a biological response in vivo, handle with caution.

  • Reconstitution
    It is recommended to reconstitute the lyophilized product in sterile deionized water to a final concentration of 1 mg/ml. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long-term storage.

  • Function

    Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation.
  • Involvement in disease

    Genetic variations in TNF are a cause of susceptibility psoriatic arthritis (PSORAS) [MIM:607507]. PSORAS is an inflammatory, seronegative arthritis associated with psoriasis. It is a heterogeneous disorder ranging from a mild, non-destructive disease to a severe, progressive, erosive arthropathy. Five types of psoriatic arthritis have been defined: asymmetrical oligoarthritis characterized by primary involvement of the small joints of the fingers or toes; asymmetrical arthritis which involves the joints of the extremities; symmetrical polyarthritis characterized by a rheumatoidlike pattern that can involve hands, wrists, ankles, and feet; arthritis mutilans, which is a rare but deforming and destructive condition; arthritis of the sacroiliac joints and spine (psoriatic spondylitis).
  • Sequence similarities

    Belongs to the tumor necrosis factor family.
  • Post-translational

    The soluble form derives from the membrane form by proteolytic processing.
    The membrane form, but not the soluble form, is phosphorylated on serine residues. Dephosphorylation of the membrane form occurs by binding to soluble TNFRSF1A/TNFR1.
    O-glycosylated; glycans contain galactose, N-acetylgalactosamine and N-acetylneuraminic acid.
  • Cellular localization

    Secreted and Cell membrane.
  • Information by UniProt


  • SDS-PAGE analysis of ab246176 under reducing conditions.

    The protein has a calculated MW of 20.2 kDa. The protein migrates as 21 kDa on a SDS-PAGE gel under reducing conditions due to glycosylation.

  • The purity of Biotinylated Mouse TNF-alpha (His Tag) Avi Tag (HPLC-verified) was greater than 90% as determined by SEC-HPLC.
  • Immobilized Human TNFR1, Fc Tag at 5 µg/mL (100 µl/well) can bind ab246176 with a linear range of 0.8-12.5 ng/mL.

  • SEC-HPLC analysis of ab246176.

    More than 90% of ab246176 presents as active trimers with a molecular mass of 60 kDa, as determined by SEC-HPLC analysis.
