Product Name | TNF-alpha (Low Endotoxin ) |
Size | 10 µg |
Description | Tumor necrosis factor alpha (TNFα or TNFSF2) is produced by many different cell types including activated monocytes, fibroblasts, endothelial cells, macrophages, T-cells, B-lymphocytes, granulocytes, smooth muscle cells, eosinophilis, chondrocytes and other cell types (1). It functions as a cytokine involved in cell proliferation, differentiation, apoptosis, lipid metabolism and coagulation (2, 3). High level of TNFα leads to the development of inflammatory responses that are hallmarks of many diseases including autoimmune diseases, insulin resistance and cancer (4, 5). The active form of TNFa (18 kDa) is generated by the cleavage of an Ala-Val bond between residues 76-77 of the precursor protein (6). |
