TNF alpha Monoclonal Antibody (MP6-XT22), Alexa Fluor™ 488, eBioscience™, Invitrogen™

Description

• Description: The MP6-XT22 antibody reacts with mouse tumor necrosis factor-alpha (TNF alpha), a 17 kDa cytokine produced by monocytes, macrophages, neutrophils, NK cells and CD4(+) T cells
• TNF alpha has cytolytic activity against a range of tumor cells and is important in immune regulation
• TNF alpha forms dimers and trimers and also exists as a 26 kDa membrane-bound form
• Applications Reported: The MP6-XT22 antibody has been reported for use in ELISA, IHC, neutralization, and immunofluorescent intracellular staining with flow cytometric analysis
• Fluorochrome conjugated MP6-XT22 antibody is recommended for use in intracellular staining
• Applications Tested: This MP6-XT22 antibody has been tested by intracellular immunofluorescent staining and flow cytometric analysis of activated splenocytes cultured in the presence of monensin
• This can be used at less than or equal to 0.12 μg per test
• A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
• Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test
• It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest
• Excitation: 488 nm; Emission: 519 nm; Laser: Blue Laser
• 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.
