Protein Tag: C-His
Uniprot: P23563
Accession: P23563
Background: Tumor necrosis factor alpha (TNFα) is the prototypic ligand of the TNF superfamily. TNFα forms a homotrimer and functions by activating two types of receptors TNF-R1 (TNF receptor type 1,p55R) and TNF-R2 (TNF receptor type 2,p75R). TNFα is a pleiotropic cytokine that is capable to promote inflammation, to induce apoptotic cell death, and to inhibit tumorigenesis and viral replication. TNFα is a potent lymphoid factor that exerts cytotoxic effects on a wide range of tumor cells and certain other target cells.
Bio Acitivity: Measure by its ability to induce cytotoxicity in PK15 cells in the presence of the actinomycin D.The ED50 for this effect is <15 pg/mL.
Sequence: Leu 77-Leu 232
Purity: > 98 % as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile PBS, pH 7.4.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution: Please refer to the printed manual for detailed information.
Endotoxin: < 0.1 EU per μg of the protein as determined by the LAL method.
Calculated MW: 18.1 kDa
Observed MW: 19 kDa
