| Description |
Recombinant TNF-a Antibody is a recombinant human IgG1 monoclonal antibody specific for human tumor necrosis factor (TNF). Recombinant TNF-a Antibody is produced by recombinant DNA technology in a Chinese Hamster Ovary mammalian cell expression system in a serum-free medium and has a molecular weight of approximately 148 kDa. |
| Protein Background |
Tumor necrosis factor is a cytokine involved in systemic inflammation and is a member of a group of cytokines that all stimulate the acute phase reaction. TNF is mainly secreted by macrophages. TNF causes apoptotic cell death, cellular proliferation, differentiation, inflammation, tumorigenesisand viral replication, TNF is also involved in lipid metabolism, and coagulation. TNF's primary role is in the regulation of immune cells.Dysregulation and, in particular, overproduction of TNF have been implicated in a variety of human diseases- autoimmune diseases, insulin resistance, and cancer. |
