    Product Description

     

    TNF-β is a potent mediator of inflammatory and immune responses. It belongs to the TNF family of ligands, and signals through TNFR1 and TNFR2. TNF-β is produced by activated T and B lymphocytes, and has similar activities to TNF-α. Like TNF-α, TNF-β is involved in the regulation of various biological processes, including cell proliferation, differentiation, apoptosis, lipid metabolism, coagulation, and neurotransmission. TNF-β forms heterotrimers with lymphotoxin-beta, which anchors TNF-β to the cell surface. TNF-β mediates the inflammatory, immunostimulatory, and antiviral response, involves in the formation of second lymphoid organs during development, has a role in apoptosis. TNF-β is produced by lymphocytes and cytotoxic for a variety of tumor cells in vitro.

    Physical Appearance

    Sterile Filtered White lyophilized (freeze-dried) powder.

    Purity

    > 96% by SDS-PAGE and HPLC analyses.

    Biological Activity

    Fully biologically active when compared to standard. The ED50 as determined by a cytotoxicity assay using murine L929 cells is less than 5 pg/ml, corresponding to a specific activity of > 2.0 × 108 IU/mg in the presence of actinomycin D.

    Endotoxin

    < 0.1 EU per 1μg of the protein by the LAL method.

    Formulation

    Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH7.4, with 0.02 % Tween-20.

    Reconstitution

    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions.

     

    Shipping and Storage

     

    The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.

    Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.

     

    Cautions

     

    Avoid repeated freeze-thaw cycles.
