Background
Tumor necrosis factor alpha (TNF-α), also known as cachectin and TNFSF1A, is the prototypic cytokine of the TNF superfamily, and is a multifunctional molecule involved in the regulation of a wide spectrum of biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation. TNF-α is produced mainly by macrophages, and large amounts of this cytokine are released in response to lipopolysaccharide, other bacterial products, and Interleukin-1 (IL-1). TNF-α is primarily produced as a type I I transmembrane protein arranged in stable homotrimers, and a soluble trimeric form of TNF-α is released via proteolytic cleavage by the metalloprotease TACE/ ADAM17. Two receptors mediating the TNF-α function have been identified, the ubiquitous TNF RI from which most signaling are derived, and the hematopoietic cell-restricted TNF RII. Upon the TNF-α trimers binding, TNF receptors also form trimers, undergo a conformational change, and enable the adaptor protein TRADD to bind to the death domain, and thus initiates the signal pathways such as the NF-kB, Jak/STAT, and the MAPK pathways, as well as the death signaling. As a major mediator of apoptosis, inflammation and immunity, TNF-α has been implicated in the pathogenesis of a variety of human diseases including autoimmune diseases, insulin resistance, and cancer.

Soluble TNF-RI Recombinant Human Protein (Gibco™)

Recombinant Human Soluble TNF-Receptor Type I (sTNF-RI) is a bioactive protein intended for use in cell culture applications. sTNF-RI is a member of the TNF-receptor superfamily. This protein is one of the major receptors for the tumor necrosis factor-alpha. This receptor can activate NF-κB, mediate apoptosis, and function as a regulator of inflammation. Antiapoptotic protein BCL2-associated athanogene 4 (BAG4/SODD) and adaptor proteins TRADD and TRAF2 have been shown to interact with this receptor, and thus play regulatory roles in the signal transduction mediated by the receptor.

Soluble TNF-RII Recombinant Human Protein (Gibco™)

Recombinant Soluble TNF-RII is a bioactive protein intended for use in cell culture applications. sTNF-RII is a member of the TNF-receptor superfamily. This protein and TNF-receptor 1 form a heterocomplex that mediates the recruitment of two anti-apoptotic proteins, c-IAP1 and c-IAP2, which possess E3 ubiquitin ligase activity. The function of IAPs in TNF-receptor signalling is unknown, however, c-IAP1 is thought to potentiate TNF-induced apoptosis by the ubiquitination and degradation of TNF-receptor-associated factor 2, which mediates anti-apoptotic signals. Knockout studies in mice also suggest a role of this protein in protecting neurons from apoptosis by stimulating antioxidative pathways.

TRAIL Recombinant Human Protein (Gibco™)

Recombinant Human TRAIL is a bioactive protein intended for use in cell culture applications. TRAIL preferentially induces apoptosis in transformed and tumor cells, but does not appear to kill normal cells although it is expressed at a significant level in most normal tissues. The binding of this protein to its receptors has been shown to trigger the activation of MAPK8/JNK, caspase 8, and caspase 3.
