Recombinant Tumor Necrosis Factor-alpha (human)
recombinant tumor necrosis factor-alpha (human)
TNF-alpha is released from macrophages, monocytes, neutrophils, T-cells (principally CD4+), NK-cells and many transformed cell lines. Soluble homotrimeric TNF-alpha released from cells by proteolysis of the integral membrane precursor form of TNF-alpha. TNF-alpha binding to some TNF-alpha receptors induces apoptosis and depending on cell type, receptor expression, and signal transduction status can induce other responses. TNF-a is involved in the inflammatory response.
