产品特性 This protein carries no "tag". The protein has a calculated MW of 17.4 kDa. The protein migrates as 18 kDa under reducing (R) condition (SDS-PAGE).
纯度 >95 % as determined by SDS-PAGE.
过滤 0.22 μm filtered
内毒素水平 Less than 0.1 EU per μg by the LAL method.
质量等级 HPLC verified
ProductDetails: Biological Activity Comment Biological Activity: The bio-activity was determined by its cytotoxcity assy using L929 Cells with 1ug/mL actinomycin D. ED50<25pg/mL, corresponding to a specific activity of >4X107 Unit/mg Gel Filtration analyisis of TNF alpha protein (ActiveMax®) and E.Coli derived TNF alpha protein

SDS-PAGE: The gel filtration analysis indicates that only HEK293 expressed TNF alpha protein is trimeric form , which has a molecular mass of 54 kDa.
背景 Tumor necrosis factor alpha (TNFα) is a cytokine produced primarily by monocytes and macrophages. It is found in synovial cells and macrophages in the tissues.The primary role of TNFα is in the regulation of immune cells. TNFα is able to induce apoptotic cell death, to induce inflammation, and to inhibit tumorigenesis and viral replication. Dysregulation of TNFα production has been implicated in a variety of human diseases, including major depression, Alzheimer's disease and cancer. Recombinant TNFα is used as an immunostimulant under the INN tasonermin. TNFα can be produced ectopically in the setting of malignancy and parallels parathyroid hormone both in causing secondary hypercalcemia and in the cancers with which excessive production is associated.
