TNF alpha Antibody (PBOTNFABI) in ELISA
ELISA analysis of TNF-alpha was performed by coating 100 µL per well of anti-bovine TNF-alpha polyclonal antibody (Product # PBOTNFAI) at a concentration of 10 µg/mL and incubating overnight at 4C. The plate was blocked for one hour using 3% bovine serum albumin (BSA) diluted in PBST. The plate was washed six times with 200 µL/well PBST, and then incubated with 100 µL per well of recombinant bovine TNF-alpha protein standards and recombinant ovine TNF-alpha in tissue culture supernatant (both Log2 dilutions starting at an unknown concentra...

Product Specific Information
PBOTNFABI targets TNF Alpha in ELISA, and WB applications and shows reactivity with bovine and ovine samples.
The PBOTNFABI immunogen is tNF alpha.
PBOTNFABI detects TNF Alpha which has a predicted molecular weight of approximately 26 kDa.
The PBOTNFABI polyclonal biotinylated bovine TNFa antibody has successfully been paired as the detection antibody in a sandwich ELISA with monoclonal capture antibody MBOTNFAI (clone E10011). Typical dilutions for sandwich ELISA include 1 µg/mL for coating and 0.125 - 0.25 µg/mL for detection.
Target Information
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.
