The polyclonal antibody recognizes the extracellular part of the mouse Tumor Necrosis Factor Receptor type 2 (TNF-RII) of the membrane-bound as well as the soluble receptor. TNF-RII (~75-80 kDa) is present on most cell types and is considered to play a prominent role in cell stimulation by TNF-alpha. TNF-alpha activates inflammatory responses, induces apoptosis, regulates cellular proliferation, and may even promote cancer progression. The effects of TNF-alpha are mediated by TNF-RI and TNF-RII, which have both distinct and overlapping downstream signaling cascades. Induction of cytotoxicity and other functions are mediated largely via TNF-RI. TNF-RI is equally well activated by both the 17 kDa soluble and 26 kDa membrane-bound form, whereas TNF-RII is efficiently activated only by the membrane bound form of TNF-alpha. Binding of the inherently trimeric TNF-alpha to TNFR1 and TNFR2 induces receptor trimerization and recruitment of several signaling proteins to the cytoplasmic domains of the receptors. Occupancy of TNFR2 results in direct recruitment of TNF Receptor Associated Factor 2 (TRAF2), which in turn recruits TRAF1.
The antibody reacts with free soluble (17 kDa) and membrane (26 kDa) human TNF-alpha. The antibody inhibits the biological activity of both forms. It does not react with receptor bound TNF-alpha. It can be a useful tool to discriminate between the membrane form of TNF expressed on producer cells and the proteolytically cleaved, soluble TNF-alpha bound to its cognate cell membrane receptors (TNF-RI and TNF-RII). For this purpose we recommend to use this antibody in combination with the anti-TNF-alpha antibody HM2026, which recognizes soluble, membrane and receptor bound TNF-alpha.

For this purpose we recommend to use this antibody in combination with the anti-TNF-alpha antibody HM2024, which recognizes only soluble and membrane TNF-alpha, but not the receptor bound TNF-alpha.
The antibody reacts with human native and recombinant TNF-alpha as assessed by ELISA. The antibody inhibits the biological activity of human native and recombinant TNF-alpha as determined with L929 cells in a cytotoxicity assay. The antibody cross reacts with rhesus and cynomolgus natural TNF-alpha and lacks crossreactivity with human lymphotoxin.

The monoclonal antibody V1q recognizes mouse tumor necrosis factor alpha (TNF-?). TNF-? is the prototype cytokine of the family of TNF-related ligands, which are based on structural and functional homologies. TNF-? is synthesized as type II transmembrane protein. TNF-? can be recognized by two different membrane receptors, namely TNF-R1 and TNF-R2. TNF-? is present in a membrane-bound (tmTNF) as well as soluble form (sTNF). The membrane-bound form of TNF-? is recognized by both TNF receptors with high affinity, whereas the soluble form is recognized more superiorly by TNF-R1. TNF-? is produced by many different cell types including macrophages, T lymphocytes, NK cells, neutrophils and endothelial cells. Cells differ in the expression of the two TNF-receptors and sTNF versus tmTNF, respectively. TNF-?, a homotrimeric 17 kDa protein, is a potent mediator of inflammatory and metabolic functions. TNF-? was originally detected as a highly cytotoxic cytokine for tumor cells, it causes tumor necrosis in vivo and shows cytolytic activity against tumor cells in vitro. Furthermore, TNF-? has been implied as central mediator in shock induced by gram negative micro-organisms. TNF-? induces on its turn the production of many other cytokines. Furthermore, TNF-? has been found in inflammatory foci such as synovial effusions in rheumatoid arthritis, systemic circulation in septic shock, parasitemia and rejection of renal transplants. The monoclonal antibody V1q recognizes both natural and recombinant TNF-? and shows neutralizing activity.

The monoclonal antibody 52B83 reacts with tumor necrosis factor alpha (TNF-alpha). TNF-alpha is a homotrimeric 17 kDa protein, that interacts with either one of the two types of TNF-receptors, termed I and II, leading to receptor cross-linking and signal transduction. The receptors differ strongly in their intra-cellular signaling pathways.<br /> TNF-alpha was originally described as a highly cytotoxic cytokine for tumor cells, it causes tumor necrosis in vivo and shows cytolytic activity against tumor cells in vitro. Furthermore,- TNF-alpha is found to be a central mediator in many inflammatory and immunological processes. It can be induced by various products of micro-organisms and by various cytokines leading to expression of a wide variety of- cytokines. The pro-inflammatory properties of- TNF-alpha play a central role in several auto-immune diseases such as rheumatoid arthritis and inhibition by neutralizing molecules have been shown to be beneficial in patients.

Multi-subunit complex of cytb6/f is a crucial component for the photosynthetic electron transport chain of higher plants, green algae and cyanobacteria. This complex is catalyzing oxidation of quinols and the reduction the reduction of plastocyanin. This reaction allows to establish the proton force required for the ATP synthesis. Four major subunits build the complex: the petA gene product corresponding to a c-type cytochrome (cytf), the petB gene product corresponding to a b-type/c?-type cytochrome with three haems (cyt b6), the petD gene product (subunit IV, or suIV), and the petC gene product, corresponding to the Rieske/Iron/sulfur protein.

PTOX (plastid terminal oxidase) is a component of electron transfer chain responsible for desaturation of phytoene, which prevents the generation of reactive oxygen species. It is involved in the differentiation of plastids: chloroplasts, amyloplasts, and etioplasts. PTOX is expressed ubiquitously in plant tissues and is located in the lumen.Synonymes: IM, IM1, immutants, AOX4, alternative oxidase 4, ubiquinol oxidase 4, chloroplastic/chromoplastic
