TNF alpha Monoclonal Antibody (1F3F3D4), eBioscience™, Invitrogen™

Description

• Description: The 1F3F3D4 antibody reacts with mouse tumor necrosis factor-alpha (TNFaalpha), a 17 kDa cytokine produced by monocytes, macrophages, neutrophils, NK cells and CD4(+) T cells
• Applications Reported: The 1F3F3D4 antibody has been reported for use in capture of mouse TNF alpha by ELISA and ELISPOT
• Applications Tested: The 1F3F3D4 antibody has been tested as the capture antibody in a sandwich ELISA for analysis of mouse TNF alpha (Tumor Necrosis Factor alpha)
• A suitable range of concentrations of this antibody for ELISA capture is 1-4 μg/mL
• Purity: Greater than 90%, as determined by SDS-PAGE
• Aggregation: Less than 10%, as determined by HPLC
• Filtration: 0.2 μm post-manufacturing filtered
• TNF alpha is a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily
• This cytokine is mainly secreted by macrophage and bind to its receptors, TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR
• TNF alpha is involved in the regulation of immune cells, cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation
• TNF alpha exists as a multimer of two, three, or five noncovalently linked units, but shows a single 17 kDa band following SDS-PAGE under non-reducing conditions
• Knockout studies in mice also suggested the neuroprotective function of TNF alpha, and has been observed to causes tumor necrosis when injected into tumor-bearing mice
• Other functions of TNF-alpha include its role in the immune response to bacterial, viral, parasitic and certain fungal infections, as well as its role in the necrosis of specific tumors
• TNF alpha causes cytolysis or cytostasis of certain transformed cells, being synergistic with interferon-gamma in its cytotoxicity
• This cytokine has been implicated in a variety of diseases, including autoimmune diseases, insulin resistance, and cancer.
