TNF p55 Receptor Polyclonal Antibody, Rockland™

Description

• Store vial at -20°C prior to opening
• Aliquot contents and freeze at -20°C or below for extended storage
• Avoid cycles of freezing and thawing
• Centrifuge product if not completely clear after standing at room temperature
• This product is stable for several weeks at 4°C as an undiluted liquid
• Dilute only prior to immediate use
• The antiserum is directed against the extracellular domain of the cell bound human TNFRp55
• In general, this antibody also detects primate sTNFRp55
• The antibody does not recognize human sTNFRp75
• In ELISA formats and other immunoreactive assays, this antibody will detect the extracellular domain of the TNFRp55 found in human body fluids, particularly in the circulation, urine and supernatants of cells and synovial fluid
• TNFR1 (Tumor necrosis factor receptor 1) belongs to the tumor necrosis factor superfamily, and is one of the major TNF-alpha receptors
• TNFR1 plays an important role in mediating, in cytokine mediated signaling, positive regulation of the NF-Kb pathway, positive regulation of angiogenesis, and negative regulation of gene expression
• The extracellular domain of TNFR1 is also released into the circulatory system as soluble TNFR1 (sTNFR1)
• In humans, the TNFR1 gene is located on chromosome 12
• Anti-apoptotic protein BCL2-associated athanogene 4 (BAG4/SODD) and adaptor proteins TRADD and TRAF2 have been shown to interact with TNFR1, and thus play regulatory roles in the signal transduction mediated by the receptor
• Germline mutations of the extracellular domains of TNFR1 were found to be associated with the autosomal dominant periodic fever syndrome, and the impaired receptor clearance is thought to be a mechanism of the disease.
