TNF alpha Monoclonal Antibody (MAb11), Alexa Fluor™ 700, eBioscience™, Invitrogen™

Description

• Description: The MAb11 antibody reacts with human tumor necrosis factor-alpha (TNF alpha), a 17 kDa cytokine produced by monocytes, macrophages, neutrophils, NK cells and CD4+ T cells
• TN 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
• The MAb11 antibody is a neutralizing antibody
• Applications Reported: This MAb11 antibody has been reported for use in intracellular staining followed by flow cytometric analysis
• Applications Tested: This MAb11 antibody has been pre-titrated and tested byintracellular staining and flow cytometric analysis of stimulated normal human peripheral blood cells using the Intracellular Fixation & Permeabilization Buffer Set (cat
• 88-8824) and protocol
• Please refer to Best Protocols: Protocol A: Two step protocol for (cytoplasmic) intracellular proteins located under the Resources Tab online
• This can be used at 5 μL (0.25 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
• Alexa Fluor™ 700 emits at 723 nm and can be excited with the red laser (633 nm)
• Most instruments will require a 685 LP mirror and 710/20 filter
• Please make sure that your instrument is capable of detecting this fluorochrome
• 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.
