Tumor Necrosis Factor alpha (TNF-alpha) is a 17.3kD multi-functional pro-inflammatory cytokine primarily secreted by macrophages, but also produced by T and B lymphocytes, activated monocytes and fibroblasts. TNF-alpha exists in both a transmembrane and mature soluble form and has many biological properties, including activation of transcription factor NF-KappaB, the induction of apoptosis in various tumor cell lines and the stimulation of cell differentiation and proliferation under certain conditions. Studies have revealed a role for TNF-alpha in inflammation, septic shock, autoimmune disease and rheumatoid arthritis. Source: Recombinant corresponding to mouse TNF-a expressed in E. coli. Molecular Weight: ~17.5kD Biological Activity: ED50 range=0.005-0.02ng/ml, determined by the dose dependent cytotoxicity of L929 cells. Optimal concentration for individual application should be determined by a dose response assay. Endotoxin: ~0.1ng/ug Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. Molecular Weight: ~17.5kD |
