Tumor Necrosis Factor (TNF), recombinant cynomolgus protein is supplied as a lyophilized powder. It is suitable for use in analysis of protein structure, and performing cell based assays. It can also be used as an immunogen, as a protein standard, or in other research applications

This recombinant protein was expressed from a DNA sequence encoding the soluble form of cynomolgus TNF-alpha (Val 77-Leu 233) fused to an initial Met at the N-terminus.

Activity: Measured in a cytotoxicity assay using L-929 mouse fibrosarcoma cells in the presence of the metabolic inhibitor actinomycin D. The ED50 is typically 20-80 pg/ml.

Formulation: Lyophilized in 50 mM Tris, 50 mM NaCl, pH 7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween 80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.
