Product Description:

Protein Description:

TNF-ض works as a potential mediator in the inflammatory and immune process. It a component of the TNF family of ligands, and signals through TNFR1 and TNFR2. TNF-ض is secreted by activated T and B lymphocytes, and has similar function to TNF-›¥. In the same manner as TNF-›¥, TNF-ض is involved in the regulation of various biological processes, including cell proliferation, differentiation, apoptosis, lipid metabolism, coagulation, and neurotransmission. TNF-ض is generally released as a soluble polypeptide. In addition, lymphotoxin-ض can anchor TNF-ض to the cell surface and form heterotrimers in an effective manner. TNF-ض is cytotoxic to a wide range of tumor cells.

Activity:

Measure by its ability to induce cytotoxicity in L929 cells in the presence of actinomycin D. The ED50 for this effect is <3 pg/mL. The specific activity of recombinant human TNF beta is > 3.3x 108 IU/mg.

Endotoxin level: <0.1 EU per 1 ug of the protein by the LAL method.

Calculated Molecular Weight: 18.65 kDa

Formulation: The protein was lyophilized from a solution containing 20 mM sodium citrate, 0.2 MNaCl, pH 3.5.

Reconstitution:

It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 ug/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

Shipping: Blue Ice

Stability and Storage:

Lyophilized protein should be stored at -20 degrees Celsius for 1 year. Upon reconstitution, store at 2 degrees Celsius to 8 degrees Celsius for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20 degrees Celsius or -80 degrees Celsius for 3-6 months.
