This extracellular domain can be proteolytically cleaved to make soluble TNF RI. The standard protein in this kit is soluble TNF RI and the capture and detector antibodies were raised against this region of TNF RI.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nThe Soluble TNF Receptor I + Fc Fragment also known as TNFRSF1A-Fc is a recombinant fusion protein with an approximate mass of 75 kDa. Mechanically this fusion protein acts by binding to tumor necrosis factor-alpha (TNF-α) inhibiting its activity and preventing interactions with cell surface TNF receptors. Soluble TNF Receptor I + Fc Fragment keeps the TNF-α activity in check by acting as a decoy receptor. It is expressed in various cells including immune cells and endothelial cells allowing it to modulate inflammatory responses effectively.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe Soluble TNF Receptor I + Fc Fragment helps regulate immune and inflammatory responses. It functions by blocking the pro-inflammatory effects of TNF-α an element pivotal in the inflammatory process. By neutralizing TNF-α it prevents the recruitment and activation of immune cells and cytokines. This protein does not function alone; it works within larger protein complexes to execute its role in cellular communication and signal transduction.\u003cbr\u003e\nPathways\u003cbr\u003e\nThis fusion protein plays a significant role in the NF-κB and apoptosis signal pathways. Within these pathways TNF-α is an important mediator whose activity is moderated by the presence of the Soluble TNF Receptor I + Fc Fragment. By inhibiting TNF-induced activation of NF-κB the fusion protein can influence processes related to cell survival and death. It is closely related to proteins such as IκB (inhibitor of NF-κB) showing how its activity can have downstream effects on a variety of signaling processes.\u003cbr\u003e\nSoluble TNF Receptor I + Fc Fragment is used therapeutically in conditions like rheumatoid arthritis and inflammatory bowel disease. These disorders involve high levels of TNF-α which contribute to excessive inflammatory responses. The fusion protein helps mitigate such conditions by decreasing the TNF-α activity which in turn lowers inflammation. Through these actions this target is also indirectly connected to the regulatory proteins involved in these disorders like interleukin-6 (IL-6) which can also influence the inflammatory process.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843567931561,"sku":"ab209881","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab209881","provider":"Iright","version":"1.0","type":"link"}
