生物活性 | Measured in a cytotoxicity assay using L-929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is 10-50 pg/mL. |
純度 | > 95% as determined by reducing SDS-PAGE. |
內(nèi)毒素 | < 1.0 EU per 1 μg as determined by LAL test. |
儲(chǔ)存條件 | Lyophilized protein should be stored at -5~-20℃, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at -5~-20℃ for 3 months. |
運(yùn)輸條件 | Ambient temperature or ice pack. |
有效期 | 12個(gè)月 |
制劑 | Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 6% Sucrose, 4% Mannitol, 0.05% Tween 80, pH 6.0. |
復(fù)融 | Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
背景介紹 | TNFα is a homotrimer with a subunit molecular mass of 17 kD Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It plays a major role in growth regulation, differentiation, inflammation, viral replication, tumorigenesis, autoimmune diseases and in viral, bacterial, fungal, and parasitic infections. Besides inducing hemorrhagic necrosis of tumors, TNF was found to be involved in tumorigenesis, tumor metastasis, viral replication, septic shock, fever, inflammation, and autoimmune diseases including Crohn’s disease, and rheumatoid arthritis as well as graft-versus-host disease. |
